[ h e p - e x ] F e b Introduction
Many theories of physics beyond the Standard Model (SM) predict the presence of new high-mass stateswhich can currently only be produced in the high-energy collisions at the Large Hadron Collider (LHC).One powerful experimental signature of these new states is a resonance in the diphoton invariant massspectrum, as this final state provides excellent invariant mass resolution which can be used to separate thesignal from the SM background processes.This Letter presents a search for new high-mass resonances decaying into two photons using 139 fb − of √ 𝑠 =
13 TeV proton–proton ( 𝑝 𝑝 ) collision data recorded by the ATLAS detector from 2015 to 2018 at theLHC. This analysis searches for a generic resonance using two benchmark signal models: a spin-0 resonantstate ( 𝑋 ), which is predicted by many models that include extensions to the Higgs sector [1–7]; and aspin-2 graviton ( 𝐺 ∗ ), taken here to be the lightest Kaluza–Klein (KK) [8] excitation in a Randall–Sundrummodel [9, 10] with one warped extra dimension (RS1). Previous searches for high-mass diphoton resonancesusing the 2015–2016 𝑝 𝑝 collision data have been reported by the ATLAS and CMS collaborations [11,12]. Modifications with respect to the analysis in Ref. [11] include a common event selection for thespin-0 and spin-2 resonance searches, the use of the functional decomposition method [13] to assess thespurious signal uncertainty, and updates to the photon reconstruction, identification, isolation and energycalibration.This search uses functional forms to describe the signal and background components in a fit of thediphoton invariant mass spectrum, 𝑚 𝛾𝛾 , to determine the signal yield. In the absence of a significant signalexcess, limits are placed on the production cross-section times branching ratio, 𝜎 × 𝐵 ( 𝑋 → 𝛾𝛾 ) . For thespin-0 case, the limits are computed in terms of the fiducial cross-section, defined as the product of thecross-section times the branching ratio to two photons within a fiducial acceptance which closely followsthe selection criteria applied to the reconstructed data. In the spin-2 analysis, limits are instead placedon the total cross-section times branching ratio to the two-photon final state. These limits are providedas a function of resonance mass and width in the spin-0 search and as a function of graviton mass andcoupling 𝑘 / 𝑀 Pl for the spin-2 resonance search. As the graviton natural width is related to the couplingvia Γ 𝐺 ∗ = . ( 𝑘 / 𝑀 Pl ) 𝑚 𝐺 ∗ , the graviton is expected to be a narrow resonance [14] for the couplingsconsidered in this search, i.e. 𝑘 / 𝑀 Pl < 0.1. The ATLAS experiment [15–17] at the LHC is a multipurpose particle detector with a forward–backwardsymmetric cylindrical geometry and a near 4 𝜋 coverage in solid angle. It consists of an inner trackingdetector surrounded by a thin superconducting solenoid providing a 2 T axial magnetic field, electromagneticand hadronic calorimeters, and a muon spectrometer. The inner tracking detector covers the pseudorapidityrange | 𝜂 | < .
5. It consists of silicon pixel, silicon microstrip, and transition radiation tracking detectors.Lead/liquid-argon (LAr) sampling calorimeters provide electromagnetic (EM) energy measurements withhigh granularity. A hadron sampling calorimeter made of steel and scintillator tiles covers the centralpseudorapidity range ( | 𝜂 | < . ATLAS uses a right-handed coordinate system with its origin at the nominal interaction point (IP) in the centre of the detectorand the 𝑧 -axis along the beam pipe. The 𝑥 -axis points from the IP to the centre of the LHC ring, and the 𝑦 -axis pointsupwards. Cylindrical coordinates ( 𝑟, 𝜙 ) are used in the transverse plane, 𝜙 being the azimuthal angle around the 𝑧 -axis.The pseudorapidity is defined in terms of the polar angle 𝜃 as 𝜂 = − ln tan ( 𝜃 / ) . Angular distance is measured in units of Δ 𝑅 ≡ √︁ ( Δ 𝜂 ) + ( Δ 𝜙 ) . | 𝜂 | = .
9. The muon spectrometer surrounds thecalorimeters and is based on three large air-core toroidal superconducting magnets with eight coils each.The field integral of the toroids ranges between 2.0 and 6.0 T m across most of the detector. A two-leveltrigger system is used to select events. The first-level trigger is implemented in hardware and uses a subsetof the detector information to keep the accepted rate below 100 kHz. A software-based trigger reduces theaccepted event rate to an average of 1 kHz depending on the data-taking conditions.
The search is carried out using the √ 𝑠 =
13 TeV 𝑝 𝑝 collision dataset with a bunch spacing of 25 ns collectedfrom 2015 to 2018, with stable beam conditions and all ATLAS subsystems operational, which correspondsto an integrated luminosity of 139 . ± . − [18]. The data were recorded using a diphoton trigger thatrequired two electromagnetic clusters with transverse energies 𝐸 T above 35 and 25 GeV, respectively, bothfulfilling photon identification criteria based on shower shapes in the electromagnetic calorimeter. Theefficiency of the diphoton trigger with respect to the full event selection is above 99% for 2015–2016 andabove 98% for 2017–2018 [19].Simulated Monte Carlo (MC) events are used to optimize the analysis selections and characterize the signaland background. Interference effects between the resonant signal and all background processes are expectedto be small for a narrow-width signal and are neglected in this analysis to keep it as model-independent aspossible.To model the spin-0 resonance signals, MC samples were generated for a hypothetical resonance mass 𝑚 𝑋 in the range 200–3000 GeV assuming a decay width Γ 𝑋 of 4 MeV to describe a hypothetical resonancein the narrow-width approximation (NWA). Four production modes were generated to assess the modeldependence of the fiducial selection. The gluon–gluon fusion (ggF) samples were generated at next-to-leading order (NLO) in pQCD using MadGraph5_aMC@NLO [20], with a set-up matching that describedin Ref. [11]. Vector-boson fusion (VBF) samples were generated at NLO in pQCD with Powheg-Boxv2 [21–23] interfaced with Pythia 8 [24] using the CT10 parton distribution function (PDF) set [25] andthe AZNLO tune [26] of the parameter values. Simulated samples for production of a scalar resonance inassociation with a vector boson or 𝑡 ¯ 𝑡 pair were generated at leading order (LO) in pQCD with Pythia 8using the NNPDF23LO PDF set [27] and the A14 tune [28]. Additional gluon–gluon fusion samples wereproduced for various fixed decay widths, ranging from 4 MeV up to 10% of 𝑚 𝑋 .To model the spin-2 resonance signals, MC samples incorporating the RS1 model were generated at LO inpQCD using Pythia 8 with the NNPDF23LO PDF set and the A14 tune, with masses 𝑚 𝐺 ∗ in the range500–5000 GeV and fixed coupling values 𝑘 / 𝑀 Pl ranging from 0.01 to 0.1.The irreducible background in this search, coming from events with two prompt photons, was simulatedusing the Sherpa [29, 30] event generator, version 2.2.4. Matrix elements were calculated with up toone additional parton at NLO and with two or three partons at LO in pQCD and merged with the Sherpaparton-shower simulation using the ME+PS@NLO prescription [31–34]. The NNPDF3.0 NNLO PDFset [35] was used in conjunction with a dedicated parton-shower tune in the Sherpa generator.The effects of multiple 𝑝 𝑝 interactions in the same bunch crossing as the hard scatter and in neighbouringones are included using simulated events generated with Pythia 8. Simulated events were weighted toreproduce the distribution of the average number of interactions per bunch crossing observed in data.3ll simulated signal events were processed using a full simulation of the ATLAS detector [36] basedon Geant4 [37]. The background 𝛾𝛾 events were processed using a fast simulation of the ATLASdetector [38], where the full simulation of the calorimeter is replaced with a parameterization of thecalorimeter response. All simulated events were reconstructed with the same reconstruction algorithms asthose used for data. Photon candidates are reconstructed from topological clusters of energy deposits in the EM calorimeterand calibrated as described in Ref. [39]. The event selection requires at least two photon candidateswith 𝐸 T >

52. The two highest- 𝐸 T photons and additional information from the tracking systems areused to identify the diphoton production vertex [40].To reduce the background from jets, photon candidates are required to fulfil tight identification criteriabased on shower shapes in the EM calorimeter and energy leakage into the hadronic calorimeter [39]. Alooser identification is considered for background estimations that benefit from a larger sample size. The tight identification is optimized in sub-ranges of photon 𝐸 T and | 𝜂 | to have an identification efficiencygreater than 90% for the 𝐸 T range considered in this analysis. The calorimeter isolation transverse energy 𝐸 isoT is required to be smaller than 0 . 𝐸 T + .
45 GeV, where 𝐸 isoT is defined as the sum of transverseenergies of the positive-energy topological clusters [41] within a cone of size Δ 𝑅 = . 𝐸 isoT is corrected for the leakage of the photonshower into the isolation cone. The contributions from the underlying event and pile-up are subtractedusing the techniques described in Refs. [42, 43]. The track isolation is defined as the scalar sum of thetransverse momenta of tracks with 𝑝 T > Δ 𝑅 = . . 𝐸 T .The diphoton invariant mass 𝑚 𝛾𝛾 is evaluated using the energies of the leading- and subleading- 𝐸 T photons, their separation Δ 𝜙 in azimuthal angle and Δ 𝜂 in pseudorapidity determined from their positionsin the calorimeter, and the position of the diphoton production vertex. Additional kinematic requirementsare placed on the photon 𝐸 T relative to the diphoton invariant mass: the leading photon must have 𝐸 T / 𝑚 𝛾𝛾 > . 𝐸 T / 𝑚 𝛾𝛾 > .
25. These requirements wereoptimized to retain improved significance with respect to Ref. [11] while allowing the analysis to have aunified selection for the spin-0 and spin-2 models. For the spin-0 model, the new selections result in aslightly worse expected limit for the NWA scalar models below 700 GeV but up to 30% better expectedlimits above. For the spin-2 model, the expected limit is improved by 15% to 70% depending on 𝑚 𝐺 ∗ .In total, 433 919 data events with 𝑚 𝛾𝛾 >

𝐸 T + Parametric models of the diphoton invariant mass distributions of the signal are used to test for different4esonance masses and Γ 𝑋 or 𝑘 / 𝑀 Pl . The detector resolution is modelled by a double-sided Crystal Ball(DSCB) function [44, 45], with parameters expressed as a function of 𝑚 𝑋 . The DSCB function is convolvedwith the true lineshape, which is parameterized as the product of a relativistic Breit–Wigner (BW) functionand mass-dependent factors accounting for the parton luminosity and the matrix elements of the processes.This convolution is performed independently for the spin-0 and spin-2 models. The lineshapes for the spin-0model are derived from the functional forms defined in the MadGraph5_aMC@NLO MC simulation of theggF process, where a BW function of width Γ 𝑋 is combined with a mass-dependent gluon–gluon luminosityfunctional form. The lineshapes for the spin-2 model are derived from the functional forms defined inthe Pythia 8 MC simulation of the RS1 model [46], where a BW function of width 1 . ( 𝑘 / 𝑀 Pl ) 𝑚 𝐺 ∗ iscombined with mass-dependent gluon–gluon and quark–antiquark luminosity functional forms. The unified spin-0 and spin-2 search selections in this analysis allow the use of a common backgroundmodelling procedure. The largest background component comes from the non-resonant production ofphoton pairs ( 𝛾𝛾 events); smaller backgrounds come from events containing a photon and a jet ( 𝛾 𝑗 events)and events with two jets ( 𝑗 𝑗 events), where the jets are misidentified as photons. The relative contributionof these processes is determined using the two-dimensional sideband method described in Ref. [47] andshown in Figure 1. The overall 𝛾𝛾 purity of the selected events increases with 𝑚 𝛾𝛾 from around 89% at150–200 GeV to around 97% above 400 GeV with an uncertainty of 3%–4%. No significant difference inpurity is seen between the LHC data-taking periods, and the remaining background is dominated by 𝛾 𝑗 events.

The total uncertainties, including statistical andsystematic components added in quadrature, are shown as error bars. 𝛾𝛾 MC events and 𝛾 𝑗 events derived from a dedicated data control region where the photonidentification requirements are inverted. The diphoton invariant mass distribution is fitted in the range above150 GeV. The lower value of the range is chosen to allow for enough events in the 𝑚 𝛾𝛾 side-bands to ensurea good description by the analytic form, while the upper value of the range is chosen such as the procedureremains stable in injection tests . The search region for a resonant signal covers the region 160–3000 GeVfor a NWA spin-0 resonance, 400–2800 GeV for a wide spin-0 resonance, and 500–2800 GeV for a gravitonresonance. The procedure described in Ref. [40] is used to ensure that the chosen analytic functionis flexible enough to model any potential variations in the background template. The analytic form ischosen from the family of functions previously used to describe the diphoton invariant mass spectrum [48].Additional background templates are constructed from variations due to the uncertainties in the measuredbackground composition, shape of the 𝛾 𝑗 component and theoretical uncertainties such as the choice ofPDF and the variation of renormalization and factorization scales. The function with the fewest degrees offreedom that maintains enough flexibility to model all variations of the template shape is chosen, and ittakes the form 𝑓 ( 𝑥 ; 𝑏, 𝑎 , 𝑎 ) = 𝑁 ( − 𝑥 / ) 𝑏 𝑥 𝑎 + 𝑎 log ( 𝑥 ) (1)where 𝑁 , 𝑏 , 𝑎 , 𝑎 are free parameters and 𝑥 = 𝑚 𝛾𝛾 /√ 𝑠 .Fits to these background templates are used to estimate the bias due to this choice of analytic function; anyfitted signal yield is considered as a ‘spurious signal’ systematic uncertainty. For lower resonance massesthis uncertainty is dominated by the statistical fluctuations of the background template due to the limitednumber of generated MC events, leading to fluctuations that are significant compared to the expectedstatistical uncertainty on the data. To suppress the impact of these fluctuations, each background templateis smoothed using the functional decomposition (FD) method [13]. This method uses a linear combinationof orthonormal exponential functions to fit a background template and the fit result is binned and used as asmoothed template for the spurious-signal determination only.To illustrate the FD process, an example fit to a pseudo-experiment and the resulting spurious-signaluncertainty is shown in Figure 2. This pseudo-experiment dataset is generated from the functional formgiven in Eq. (1), where the parameters are determined by fitting simulated 𝛾𝛾 events. First, the FDmethod is used to fit the pseudo-experiment, resulting in a smoothed FD template; this template and thepseudo-experiment are shown in Fig. 2(a). The spurious signal estimated by fitting the smoothed FDtemplate with the signal-plus-background model has fewer fluctuations and a smaller amplitude than the oneestimated by fitting the unsmoothed template as shown in Fig. 2(b). To verify that the smoothing maintainsthe underlying shape of the 𝑚 𝛾𝛾 distribution, this process is repeated for an ensemble of pseudo-experimentsand the mean number of extracted signal events is compared between the smoothed and unsmoothedtemplates. The resulting bias in the determination of the spurious-signal uncertainty, shown in Fig. 2(c),agrees between the unsmoothed and smoothed template ensembles and is found to be much smaller thanthe uncertainty from a single pseudo-experiment. Finally, by using this smoothed template approach, animproved description of the spurious-signal uncertainty is obtained, leading to an improvement of 2–28%in the expected sensitivity of this search as shown in Fig. 2(d).The spurious-signal uncertainty for this background function choice is 40%–10% of the statistical uncertaintyof the fitted signal yield for NWA signals with masses ranging from 160 GeV to 3000 GeV. This uncertaintyincreases to 70%–20% for wider signals with masses ranging from 400 GeV to 2800 GeV.6 −

The use of smoothed templates leads to a limit improvement of 2–28%. Statistical procedure
The statistical analysis of the data uses binned maximum-likelihood fits of the 𝑚 𝛾𝛾 distribution. Thesystematic uncertainties listed in Table 1 are accounted for in the fits by using nuisance parametersconstrained by Gaussian penalty terms in the likelihood function. They include the experimentaluncertainties in the luminosity determination, pile-up profile, trigger efficiency, and photon identificationand reconstruction. Additional systematic uncertainties in the signal shape come from the uncertainties inthe photon energy resolution and scale. For the spin-0 model, the correction factors inside the fiducialvolume, used to compute the limit on the fiducial cross-section, are determined using gluon–gluon fusionMC events and are compared with the ones computed for the other production modes, leading to a smallmass-dependent systematic bias in the signal yield.A local 𝑝 -value ( 𝑝 ) for the background-only hypothesis is calculated using the asymptotic approxima-tion [49]. Global significance values are computed using background-only pseudo-experiments to accountfor the trial factors because the searches scan both the signal mass and a range of width (coupling)hypotheses. For these calculations, a maximum-likelihood fit is performed on each pseudo-experimentwith the signal mass, width, and signal rate as free parameters within a specific search range. For the spin-0case, the search ranges are defined to be 𝑚 𝑋 = [ , ] GeV and Γ 𝑋 / 𝑚 𝑋 = [ , ] ; the spin-2 caseis restricted to the ranges 𝑚 𝐺 ∗ = [ , ] GeV and 𝑘 / 𝑀 Pl = [ . , . ] .In the absence of a signal, the expected and observed 95% confidence level (CL) exclusion limits on thecross-section times branching ratio to two photons are computed using a modified frequentist approachCL s [50, 51], assuming the asymptotic approximation for the test-statistic distribution. In regions wherevery few events are observed and the expected signal yield is also small, the asymptotic approximationis found to deviate from the limits based on pseudo-experiments. To account for this effect, for massesgreater than 1000 GeV, pseudo-experiments are used to verify the expected and observed limits, and usedin place of the asymptotic limit where differences are observed.For the spin-2 model, the limits on the total production cross-section can be translated into a lower limit onthe graviton mass. For that purpose the spin-2 exclusion limits are extended up to 𝑚 𝐺 ∗ = The diphoton invariant mass distribution of the events passing the selection is shown in Figure 3, along withthe background-only fit. The highest-mass diphoton candidate selected in data has a mass of 2.36 TeV.The probability of compatibility with the background-only hypothesis, quantified with the local 𝑝 -valueexpressed in standard deviations, is shown in Figure 4 as a function of the hypothesized resonance massand width. The most significant excess is observed for a mass of (cid:39)

01 model, corresponding to a 3 . 𝜎 local significance. The correspondingglobal significance is 1 . 𝜎 and 1 . 𝜎 for the two models, respectively.The observed and expected limits, shown in Figure 5 for two values of the signal width, are in goodagreement, consistent with the absence of a signal. The observed limits for different masses and differentvalues of Γ 𝑋 / 𝑚 𝑋 or 𝑘 / 𝑀 Pl are summarized in Table 2.

Searches for new resonances in high-mass diphoton final states with the ATLAS experiment at the LHCare presented. The searches use the full LHC Run 2 proton–proton collision dataset at a centre-of-massenergy of √ 𝑠 =
13 TeV, corresponding to an integrated luminosity of 139 fb − . The analyses are optimizedto search for spin-0 resonances with masses above 200 GeV and for spin-2 resonances predicted by theRandall–Sundrum model with masses above 500 GeV.The data are consistent with the Standard Model background expectation.
