Measurement of the jet mass distribution and top quarkmass in hadronic decays of boosted top quarks in ppcollisions at √ s =
13 TeV
The CMS Collaboration ∗ Abstract
A measurement is reported of the jet mass distribution in hadronic decays of boostedtop quarks produced in pp collisions at √ s =
13 TeV. The data were collected with theCMS detector at the LHC and correspond to an integrated luminosity of 35.9 fb − . Themeasurement is performed in the lepton+jets channel of tt events, where the lepton isan electron or muon. The products of the hadronic top quark decay t → bW → bqq (cid:48) are reconstructed as a single jet with transverse momentum larger than 400 GeV. Thett cross section as a function of the jet mass is unfolded at the particle level and usedto extract a value of the top quark mass of 172.6 ± ”Published in Physical Review Letters as doi:10.1103/PhysRevLett.124.202001 .” c (cid:13) ∗ See Appendix A for the list of collaboration members a r X i v : . [ h e p - e x ] M a y The top quark is the most massive known elementary particle. Its large mass m t leads to sig-nificant contributions from quantum corrections to the mass of the Higgs boson and precisionobservables in the electroweak sector. As a consequence, the top quark plays an important rolein the mechanism of electroweak symmetry breaking. Precision measurements of m t providea crucial input for consistency checks of the standard model [1, 2]. Direct measurements of m t at the CERN LHC reach a precision of around 0.5 GeV [3–9]. However, an ambiguity in theinterpretation of the results originates from the modeling of parton-shower dynamics and non-perturbative effects in quantum chromodynamics (QCD). The result can depend on the MonteCarlo (MC) event generator, the tuning of its free parameters, and on the observables used [10].Precisely relating the experimentally obtained value of m t to the pole mass or a mass in anotherwell-defined renormalization scheme is therefore difficult from first principles [11].As an alternative, a value of the pole mass can be extracted through measurements of the to-tal [12–15] and differential [16, 17] tt production cross sections, with a precision of approx-imately 1 GeV. These measurements are dominated by tt threshold production, where un-certainties due to parton distribution functions (PDFs) and higher-order QCD corrections areimportant [18–20]. Another way to determine m t involves measuring top quarks producedwith large Lorentz boosts, where the decay products t → bW → bqq (cid:48) are contained in a sin-gle jet. The jet mass ( m jet ) peak location is sensitive to m t , and can be calculated from firstprinciples [21–27] in soft-collinear effective theory [28–31].A past measurement reporting the tt cross section as a function of m jet in the (cid:96) +jets finalstate, where (cid:96) is an electron or muon, was carried out in proton-proton (pp) collisions at √ s = m jet distribution in pp colli-sions at 13 TeV using several important improvements, including jet clustering with the XConealgorithm [33], used for the first time in an LHC analysis, and an improved unfolding proce-dure using sideband regions with high granularity.The central feature of the CMS apparatus is a superconducting solenoid of 6 m internal diame-ter, providing a magnetic field of 3.8 T. A silicon pixel and strip tracker, a lead tungstate crystalelectromagnetic calorimeter (ECAL), and a brass and scintillator hadron calorimeter, each com-posed of a central barrel and two end sections, reside within the solenoid volume. Forwardcalorimeters extend the pseudorapidity ( η ) coverage provided by the barrel and end detectors.Muons are detected in gas-ionization chambers embedded in the steel flux-return yoke outsidethe solenoid. A more detailed description of the CMS detector, together with a definition ofthe coordinate system, can be found in Ref. [34]. The particle-flow (PF) algorithm [35] aims toreconstruct and identify each individual particle in an event, using an optimized combinationof information from the various elements of the CMS detector. The candidate vertex with thelargest sum of the square of the transverse momenta p of the physics objects is taken to bethe primary pp interaction vertex; more details are given in Section 9.4.1 of Ref. [36]. FromPF candidates, jets are reconstructed using the anti- k T [37] or the XCone [33] algorithm as im-plemented in the F AST J ET software package [38]. The anti- k T jets are obtained using a distanceparameter of 0.4. In the jet clustering procedure, charged PF candidates are excluded if they areassociated to vertices from additional inelastic pp interactions within the same bunch crossing(pileup).The POWHEG [39–44] v2 generator is used for simulating tt production at next-to-leading order(NLO). Alternatively, tt production is simulated with M AD G RAPH MC @ NLO v2.2.2 [45, 46]at NLO to check a potential generator dependence of the measured cross sections. Backgroundevents resulting from the production of single top quarks are also generated in
POWHEG atNLO, where spin correlations are taken into account [47]. The production of a W boson with ad- ditional jets is simulated using M AD G RAPH MC @ NLO at NLO. Events from Drell–Yan (DY)production with additional jets are simulated in M AD G RAPH MC @ NLO at leading order (LO)and are normalized to the next-to-next-to-leading-order cross section [48]. The simulation ofthe production of two heavy gauge bosons with additional jets is performed at LO with
PYTHIA v8.212 [49]. Events in which jets are produced only through QCD interactions are also simu-lated with
PYTHIA at LO.In simulated M AD G RAPH MC @ NLO events the matrix element (ME) calculations at NLO andLO accuracy are matched to parton showers with the FxFx [50] and MLM [51] algorithms, re-spectively. The parton shower, hadronization process, and multiple-parton interactions (MPI)are simulated using
PYTHIA . The NNPDF3.0 [52] PDFs at LO and NLO are used for the respec-tive processes simulated at LO and NLO. The UE tune CUETP8M2T4 [53] is used to simulatett and single top quark production in the t channel; all other processes are simulated usingCUETP8M1 [54, 55]. The detector response is simulated with the G EANT − [58]. Events containing the decay of a top quark to a final state includinga muon are selected using a single-muon trigger [59] that requires the presence of at least onemuon candidate with a transverse momentum p T >
50 GeV and | η | < p T >
27 GeV, or an electron candidate without an isolation requirement but with p T >
115 GeVand | η | < p T >
175 GeV and | η | < p T are selected with highefficiency.Lepton candidates (electrons or muons) must have p T >
55 GeV, | η | < p T <
120 GeV must pass an isolation require-ment [60], where the isolation is defined as the p T sum of charged hadrons and neutral particlesin a cone with radius ∆ R = ∆ R = √ ( ∆ η ) + ( ∆ φ ) , where φ is the azimuthal angle in radians. Electrons with p T >
120 GeV and muons with p T >
55 GeV are required to pass a two-dimensional selectionof either ∆ R ( (cid:96) , j ) > p T, rel ( (cid:96) , j ) >
40 GeV, where j is the anti- k T jet with minimal angu-lar separation ∆ R from the lepton (cid:96) , and p T, rel ( (cid:96) , j ) is the component of the lepton momentumorthogonal to the anti- k T -jet axis [61, 62]. Each selected event must contain a single lepton.The XCone jets are obtained through a two-step jet clustering [63]. First, the exclusive XConealgorithm is applied with a distance parameter of R jet = R sub = N sub =
3. Subjets are only consideredif they are within | η | < N sub = → bW → b (cid:96) ν . The four-momentum of thelepton candidate is subtracted from the four-momentum of the anti- k T jet or XCone subjet if ∆ R ( (cid:96) , j ) < k T jets are applied to anti- k T jetsand XCone subjets. The jet energy resolution in simulated events is smeared to match theresolution in data. An additional correction applied to the XCone-subjet momenta is obtainedfrom simulated tt events in the all-jets channel to account for differences between the XCone- [GeV] m E v en t s / G e V DatattSingle tW+jetsTotal unc.

This correction is parametrized as a functionof XCone subjet p T and | η | , and has an average size of 2%, with an average uncertainty of 0.3%.The four-momenta of the three XCone subjets are combined to form the final XCone jet. TheXCone jet used to perform the measurement is the one with the largest distance ∆ R to theselected lepton. Each of the three XCone subjets in this jet must have p T >
30 GeV. The XCone-jet mass m jet is the invariant mass of all PF candidates clustered into the three XCone subjets.In order to identify jets originating from the hadronization of b quarks, the combined sec-ondary vertex v2 (CSVv2) [65] algorithm is applied to the anti- k T jets. These candidate b jetsare required to have p T >
30 GeV and | η | < − s. The kinematic phasespace of this region is defined through tt events containing one lepton with p (cid:96) T >
60 GeV,which originates from the decay of a W boson; the τ lepton decays are not considered partof the signal. Particle-level jets are obtained with a clustering identical to the one in data. Theparticle-level XCone jet with largest distance ∆ R to the lepton is required to have p T >
400 GeV,and each of its XCone subjets must have p T >
30 GeV. Its mass has to be greater than themass obtained by summing the four-momenta of the second-highest XCone jet in p T and thelepton. The resulting distribution in m jet at the particle level has a width half as large as forCambridge–Aachen (CA) jets [66, 67] with R jet = At the reconstruction level the same criteria are used as in the definition of the fiducial phasespace at the particle level. In addition, at the reconstruction level an event has to have at leastone b-tagged anti- k T jet and p missT >
50 GeV, which suppresses non-tt backgrounds. Here, p missT is the magnitude of the negative vector sum of the transverse momenta of the PF candidatesin an event [72]. The resulting m jet distribution for XCone jets with p jetT >
400 GeV is displayedin Fig. 1. Backgrounds originate from singly produced top quarks and from W+jets events.Contributions from DY+jets, diboson, and QCD multijet production are found to be negligible.The tt simulation is scaled, such that the number of simulated events matches the number ofbackground-subtracted events in data. The distribution shows a pronounced and narrow peakclose to the value of m t . The XCone-jet reconstruction results in a large improvement of theexperimental resolution in m jet . With XCone a resolution of 6% is achieved, compared to aresolution of approximately 14% for CA jets with R jet = NFOLD [73] framework. The optimal regularization strengthis determined through a minimization of the average global correlation coefficient in the outputbins [74]. The response matrix is evaluated by using tt events simulated with
POWHEG thatpass the particle- or reconstruction-level requirements. Prior to the unfolding, contributionsfrom background processes are subtracted from data. Sideband regions are included in theunfolding process to constrain migrations into and out of the measurement phase space. Fivesideband regions are defined by the requirements: 55 < p (cid:96) T <
60 GeV, 350 < p jetT <
400 GeV, atleast one XCone subjet with p T <
30 GeV, m jet less than the mass of the second XCone jet andlepton system, and at least one anti- k T jet passing a looser b tagging requirement with no anti- k T jet passing the tight b tagging requirement. In addition, the measurement region is dividedinto three bins in p jetT . Except for the sideband with a looser b tag, all sideband selections havecorresponding selections at the particle level in the evaluation of the migration matrix. In thismatrix, the number of bins in m jet at the particle level is larger than the number of bins in whichthe final measurement is presented. This helps to reduce the dependence on variations in signalmodeling through a more precise determination of migration effects. The electron and muonchannels are combined before the unfolding to increase the statistical precision, but are alsounfolded separately to verify their consistency.Experimental uncertainties are estimated using simulation and propagated through the unfold-ing process. We consider uncertainties in the pileup reweighting [75], trigger, lepton identifi-cation and b tagging [65] efficiencies, and also those related to the jet energy scale [64] and jetenergy resolution for anti- k T jets and XCone subjets, and additional XCone-subjet corrections.Uncertainties related to the integrated luminosity [58] and the production cross sections of allsignificant background processes [76–81] are also included. Uncertainties arising from choicesin modeling signal include changes made in renormalization and factorization scales µ R and µ F , changes in m t by ± h damp [53]. The uncertainty related to modeling the UEis estimated by changing the model of color reconnection in PYTHIA [82] and using two otherschemes [83, 84]. Uncertainties from modeling b quark fragmentation and the semileptonicbranching fractions of b hadrons are found to be negligible.The measured differential cross section in data is shown in Fig. 2 (left) and compared to the pre-dictions from

POWHEG is 680 ±
109 fb, where the theoretical un-certainty is obtained by changing the scales µ R and µ F , the ISR and FSR PS scales, the parameter h damp , and the UE modeling in simulation. A smaller cross section is observed in data relativeto simulation, in agreement with previous high- p T top quark measurements [32, 85–88].Figure 2 (right) shows the normalized differential cross section as a function of m jet , whichis obtained by dividing the differential cross section by the total cross section in the fiducialregion. The normalized differential cross section benefits from a partial cancellation of system-atic uncertainties and shows good agreement with the prediction from POWHEG for a value of m t = m t . A fit is performedbased on the χ evaluated as χ = d T V − d , where d is the vector of differences between themeasured normalized cross sections and the predictions obtained from POWHEG for differentvalues of m t . The symbol V represents the covariance matrix that contains statistical, experi-mental systematic, signal modeling in the unfolding, and theoretical uncertainties. The resultis m t = ± ± ± ± m t from decays of boosted top quarks, with an average energyscale of approximately 480 GeV, much larger than the scale in m t measurements from thresholdproduction. The improvement in precision by a factor of 3.6 relative to the measurement at8 TeV [32] is attributed primarily to the novel jet reconstruction using XCone. The improvementby a factor of two in both, the m jet width at the particle level and experimental resolution, together with more integrated luminosity and an increased value of √ s , provides a reductionby a factor of about 14 in the statistical uncertainty.The systematic uncertainties are also reduced through the XCone-jet reconstruction, which en-ables a more precise calibration of the XCone-subjet energies and a better stability against con-tributions from pileup and the UE. Uncertainties from modeling are reduced through the useof additional sideband regions with higher granularity in the unfolding.In summary, a measurement has been presented of the tt differential cross section for t → bW → bqq (cid:48) decays of boosted top quarks as a function of the jet mass m jet . A determinationof m t from the normalized m jet distribution provides a value of 172.6 ± m t . The differential cross section as a function of m jet will enable a determination of m t using precise analytical calculations, feasible only in the boosted regime [26]. This is animportant step in understanding the ambiguities arising between the top quark pole mass and m t measurements at hadron colliders. The novel reconstruction technique using the XConejet algorithm results in the accuracy necessary for precision measurements at large top quarkmomenta, which will become increasingly important in future work at the LHC.
