Differential cross sections are reported as a function ofHiggs boson transverse momentum, Higgs boson rapidity, number of jets in the event, and transversemomentum of the leading jet.

This Letter presents measurements of the total anddifferential cross sections of inclusive Higgs boson pro-duction using 20 . − of pp collisions produced by theLarge Hadron Collider (LHC) [1] at a center-of-mass en-ergy of √ s = 8 TeV and recorded by the ATLAS detec-tor [2]. The measured cross sections probe the propertiesof the Higgs boson and can be directly compared to thetheoretical modeling of different Higgs boson productionmechanisms, such as the most recent gluon fusion (ggF)QCD calculations. They can also be used to constrainnew physics scenarios, for example using the effectivefield theory framework as proposed in Refs. [3–7]. Theanalysis uses event yields measured in the H → γγ and H → ZZ ∗ → (cid:96) decays and detector efficiencies, both de-termined as described in Refs. [8, 9]. The statistical un-certainties on the Higgs boson signal yields in both chan-nels are larger than the systematic uncertainties, whilethe total uncertainties in the two channels are similar.Combining the analyses improves the precision of thecross-section measurements by up to 40%, and by 25-30%on average, with respect to the corresponding measure-ments in the most precise individual channel.Distributions of the differential pp → H cross sectionsare reported as a function of the transverse momentum p HT and the rapidity | y H | of the Higgs boson, the jet multi-plicity N jets , and the transverse momentum of the lead-ing jet p j1T . The observables p HT and | y H | describe thekinematics of the Higgs boson. They are sensitive toperturbative QCD modeling in ggF production, which isthe dominant Higgs boson production mechanism in theStandard Model (SM). The | y H | distribution furthermoreoffers a clean probe of the gluon parton distribution func-tion (PDF) and will play a role in future PDF fits. The N jets and p j1T observables probe the theoretical modelingof partonic radiation in ggF production as well as theoverall rate and modeling of jets in vector-boson fusion(VBF) and associated Higgs boson production ( VH and t ¯ tH ). Jets produced in VBF, VH and t ¯ tH processes tend to have higher transverse momenta than those producedvia ggF production, however the sensitivity to measuringthese contributions is weak with the current amount ofdata.Cross sections are extracted using a combined like-lihood built from the signal yields in the H → γγ channel and the data and background yields in the H → ZZ ∗ → (cid:96) channel, as well as detector efficiencies,fiducial acceptances and SM branching fractions [10]. Acomplementary approach, using a separate likelihood,measures the shape of the differential distributions byimposing a unity normalization constraint, which re-moves the implicit SM assumption on the branching frac-tions. For the extraction of the signal yields and the cor-rections of detector efficiencies, it is assumed that thesignal in both channels is due to a narrow resonancewith a mass m H = 125 . ± .
41 GeV as measured bythe ATLAS Collaboration [11]. The signal yield in the H → γγ channel is obtained from fits to the diphotonmass spectra [8], and from the background subtracteddata yield in a m (cid:96) mass window of 118 to 129 GeV forthe H → ZZ ∗ → (cid:96) channel [9]. The fiducial acceptancein both channels [8, 9] is derived using a set of MonteCarlo (MC) event generators. Powheg-box [12–14], in-terfaced with
Pythia
Pythia VH and associated production with top quarks( t ¯ tH ) and b -quarks ( b ¯ bH ). The fiducial acceptance forevents with | y H | < . H → γγ ,and 55–59% for H → ZZ ∗ → (cid:96) . For higher | y H | , the ac-ceptance decreases to 35–38% in both channels. The fidu-cial acceptance is more constant as a function of the othervariables and is in the range 56–62% for the H → γγ channel and 44–53% for the H → ZZ ∗ → (cid:96) channel.After correcting the differential cross sections and nor-malized shapes for fiducial acceptance and branchingfractions, the corresponding measurements in both chan-nels are found to be in good agreement with each other; p -values obtained from χ compatibility tests are in therange 56–99%.In the binned maximum-likelihood fit, the statisti-cal uncertainty of the H → γγ event yield is modeledusing a Gaussian distribution, while the event yieldin the H → ZZ ∗ → (cid:96) channel follows a Poisson dis-tribution due to the small sample size. Experimen-tal and theoretical systematic uncertainties affecting thesignal yields, detector efficiencies, branching fractionsand fiducial acceptance corrections are taken into ac-count in the likelihood as constrained nuisance param-eters. Nuisance parameters describing the same uncer-tainty sources are treated as fully correlated betweenbins and channels. Systematic uncertainties on the H → γγ and H → ZZ ∗ → (cid:96) background estimates andefficiency correction factors, as well as the uncertaintyon the integrated luminosity, are described in detail inRefs. [8, 9]. The branching fraction uncertainty due tothe assumed quark masses and other theoretical uncer-tainties are evaluated following the recommendations ofRef. [16], considering uncertainty correlations betweenthe H → γγ and H → ZZ ∗ → (cid:96) decay channels. Un-certainties on the acceptance correction related to thechoice of PDF set are evaluated by taking the envelopeof the sum in quadratures of eigenvector variations ofthe baseline (CT10 [17]) and the central values of alter-native (MSTW2008NLO [18] and NNPDF2.3 [19]) PDFsets. Uncertainties on the acceptance correction asso-ciated with missing higher-order corrections are evalu-ated by varying the renormalization and factorizationscales coherently and individually by factors of 0.5 and2 from their nominal values, and by reweighting the p HT distribution from Powheg-box to the prediction of the
HRes p HT reweighting is used as the systematic variation. Toaccount for the uncertainty in the mass measurement,the Higgs boson mass is varied by ± . VH fractions are varied by factors of0.5 and 2 from the SM prediction and the fraction of t ¯ tH is varied by factors of 0 and 5. These factors are basedon current experimental bounds [22–26]. The total un-certainties on the acceptance correction range from 1%to 6%, depending on the channel, distribution and bin .The total systematic uncertainties on the combined dif-ferential cross sections range from 4% to 12%, dependingon the distribution and bin. For the kinematic variables p HT and | y H | , the largest systematic uncertainties on thedifferential cross sections are due to the luminosity andthe background estimates in both channels. For the jetvariables N jets and p j1T , the largest systematic uncertain-ties on the differential cross sections are due to the jet en-ergy scale and resolution. In the shape combination, thenormalization uncertainties including luminosity, branch-ing fractions, and efficiency uncertainties do not apply.

[10], is ac-curate to next-to-next-to-leading order (NNLO) in QCDand utilises threshold resummation accurate to next-to-next-to-leading logarithms (NNLL). A significant efforthas been undertaken by the theory community to provideggF cross sections beyond this precision through variousimprovements in the perturbative calculations [31, 47–51]. Recently, the ADDFGHLM group has provided afixed-order calculation accurate to next-to-next-to-next-leading order (N LO) [27–30]. A PDF uncertainty of +7 . − . % is assigned to the LHC-XS prediction, derived fol-lowing the recommendations in Ref. [16]. This uncer-tainty is increased by +0 . − . % for the ADDFGHLM pre-diction corresponding to the change in uncertainty of theMSTW2008nnlo PDF set when changing the calculationfrom NNLO to N LO. The PDF uncertainty is treatedas uncorrelated with the QCD scale uncertainty.The central value of the measured total cross sectionis larger than the SM predictions presented in Fig. 1.A likelihood-ratio test statistic is used to quantify theagreement, using a bifurcated Gaussian to model theasymmetric theory uncertainties. The resulting p -valuesare 5 .

The ratio of the measured cross section to theLHC-XS prediction is higher than the results presentedin Refs. [22, 23, 58], which use an event categorizationbased on the expected SM yields in the different Higgsboson production modes.The larger Higgs event yield observed in data moti-vates measurements of differential cross sections to in-vestigate if the excess is localized to specific kinematicregions.

The ML-merged ggFpredictions also have uncertainties due to the choice ofmerging scale. The SHERPA uncertainties further in-clude resummation scale variations. The measured crosssections are higher than the predictions for all measuredjet multiplicities. The poorest agreement between dataand predictions can be found in the inclusive and exclu-sive 1-jet bins, with local p -values ranging between 0.1%and 3.6%. Normalizing the total expected cross sectionto the data results in an improved agreement for thesebins, with local p-values ranging from 4-29%.The combined differential cross sections as a functionof p HT , | y H | , and p j1T are shown in Fig. 3 (left).

The measured variables are the Higgs boson transversemomentum p HT (top) and its rapidity | y H | (middle), and the transverse momentum of the leading jet p j1T (bottom). The 0–30 GeVbin of the p j1T distributions corresponds to events without jets above 30 GeV. Various theoretical predictions are presented,using the same bin widths as the measurement. SHERPA 2.1.1, and MG5 aMC@NLO, as well as the
HRes calculation. The uncertainties on the predictedshapes are evaluated following the same approach as forthe differential cross-section predictions. They are de-rived from the impact of QCD scale, merging scale andPDF variations. The mean of the measured p HT distri-bution is 40 . ± . p -values quantifying the compatibility of the mea-sured cross sections and predictions range from 2% to26%, and for the shapes from 8% to 88%. For the calcula-tion of these values, the theory uncertainties are assumedto be Gaussian distributed and fully correlated betweenbins.In conclusion, this Letter presents the first measure-ments of total and differential cross sections and shapesfor inclusive pp → H production. The measurementswere performed in the H → γγ and H → ZZ ∗ → (cid:96) channels using the full 2012 dataset, which consists of20.3 fb − of pp collisions produced by the LHC at acenter-of-mass energy of √ s = 8 TeV and recorded bythe ATLAS detector. The results of the two channelsare compatible and have similar precision. The measure-ments indicate that the total production cross section ofthe Higgs boson is larger, and that it is produced withlarger transverse momentum and more associated jetsthan predicted by the current most advanced SM cal-culations, however more data is needed to confirm theseobservations.We thank CERN for the very successful operation ofthe LHC, as well as the support staff from our institutionswithout whom ATLAS could not be operated efficiently.We acknowledge the support of ANPCyT, Argentina;YerPhI, Armenia; ARC, Australia; BMWFW and FWF,Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPqand FAPESP, Brazil; NSERC, NRC and CFI, Canada;CERN; CONICYT, Chile; CAS, MOST and NSFC,China; COLCIENCIAS, Colombia; MSMT CR, MPOCR and VSC CR, Czech Republic; DNRF, DNSRCand Lundbeck Foundation, Denmark; EPLANET, ERCand NSRF, European Union; IN2P3-CNRS, CEA-DSM/IRFU, France; GNSF, Georgia; BMBF, DFG,HGF, MPG and AvH Foundation, Germany; GSRT andNSRF, Greece; RGC, Hong Kong SAR, China; ISF,MINERVA, GIF, I-CORE and Benoziyo Center, Israel;INFN, Italy; MEXT and JSPS, Japan; CNRST, Mo-rocco; FOM and NWO, Netherlands; BRF and RCN,Norway; MNiSW and NCN, Poland; GRICES and FCT,Portugal; MNE/IFA, Romania; MES of Russia and NRCKI, Russian Federation; JINR; MSTD, Serbia; MSSR,Slovakia; ARRS and MIZˇS, Slovenia; DST/NRF, SouthAfrica; MINECO, Spain; SRC and Wallenberg Foun-dation, Sweden; SER, SNSF and Cantons of Bern andGeneva, Switzerland; NSC, Taiwan; TAEK, Turkey;STFC, the Royal Society and Leverhulme Trust, United Kingdom; DOE and NSF, United States of America.The crucial computing support from all WLCG part-ners is acknowledged gratefully, in particular fromCERN and the ATLAS Tier-1 facilities at TRIUMF(Canada), NDGF (Denmark, Norway, Sweden), CC-IN2P3 (France), KIT/GridKA (Germany), INFN-CNAF(Italy), NL-T1 (Netherlands), PIC (Spain), ASGC (Tai-wan), RAL (UK) and BNL (USA) and in the Tier-2 fa-cilities worldwide.

The x -axis points from the IP to the center of theLHC ring, and the y -axis points upward. Cylindricalcoordinates ( r, φ ) are used in the transverse plane, φ being the azimuthal angle around the beam pipe. Thepseudorapidity is defined in terms of the polar angle θ as η = − θ/ (2001) 010.[55] ATLAS Collaboration, ATL-PHYS-PUB-2011-014. https://cds.cern.ch/record/1400677 .[56] ATLAS Collaboration, ATL-PHYS-PUB-2011-009. https://cds.cern.ch/record/1363300 .[57] ATLAS Collaboration, ATL-PHYS-PUB-2011-008. https://cds.cern.ch/record/1345343 .[58] V.

SUPPLEMENTAL MATERIAL
The fiducial cross section σ i in a given bin i can beexpressed as σ i = n i L B α i c i = σ fid ,i B α i , (1)where n i is the measured Higgs boson signal yield, L isthe integrated luminosity (20 . − for this analysis), B is the branching ratio (0 . H → γγ and 0 . H → ZZ ∗ → (cid:96) , (cid:96) = e or µ ), α i is the fiducial accep-tance and c i is a correction factor for detector effects, pri-marily accounting for reconstruction efficiency but alsofor bin-to-bin migration. For H → ZZ ∗ → (cid:96) , the signalyield is defined as the number of observed events n data in a window around the Higgs boson mass peak minusthe background estimate: n i = n data ,i − n bkg ,i , whilefor H → γγ , the signal yield is extracted from a simul-taneous signal+background fit of the m γγ distribution.The correction factors for detector effects c i , along withtheir systematic uncertainties are taken from the differ-ential cross section measurements in the individual chan-nels [8, 9]. The differential cross section is defined as thefiducial cross section divided by the bin width. TABLE II.

For each bin i , the acceptance factor for each decaychannel is defined as α i = σ fid ,i σ incl ,i . (2)The fiducial acceptances for both channels and all mea-sured distributions are presented in Fig. 4 and Tables IIand III. They are based on Eq. 2 and derived using theHiggs MC samples described in the text. For p HT and | y H | , α i is the probability for an event to pass the fiducial re-quirements. The acceptance is lower for H → ZZ ∗ → (cid:96) than for H → γγ since it is less likely for four decay prod-ucts to fulfill the fiducial requirements. For the jet vari-ables p j1T and N jets , an additional migration effect en-ters due to overlap between jets and the Higgs boson de-cay products, which affects the fiducial regions differentlythan the total phase space, where no Higgs boson decayproducts need to be considered. The fiducial acceptancefalls off steeply as the Higgs boson rapidity increases, asboth fiducial definitions include pseudo-rapidity require-ments on the Higgs boson decay products. Additional figures
Figure 5 presents the measured jet multiplicity distri-butions. The lower two subfigures include the individual H → γγ and H → ZZ ∗ → (cid:96) measurements. Figure 6presents the same six distributions as shown in Fig. 3,but with the individual channel measurements overlaid.1 [GeV] TH p a F i du c i a l a cc ep t an c e , Simulation

The factors are derived using Powheg for ggF and VBF production and
Pythia VH , t ¯ tH , and b ¯ bH . The width of the band indicates the uncertainty from five sources: missing higher ordercorrections, PDF variations, changing the Higgs boson mass and the production mode composition, and variations of thehadronization/underlying event tunes (see main text for further details). The PDF uncertainty is the largest individualcontribution to the total uncertainty. [ pb ] s XH Y +P NLOPS N XH Y +P MG5_aMC@NLO XH + HERPA 2.1.1 S XH STWZ + XH BLPTW + XH LHC-XS +

Figure 7 shows the measurement of the Higgs bosonproduction cross section compared to a range of theorypredictions, including LHC-XS, the result used by theATLAS and CMS collaboration in Run 1, for which theggF part is accurate to NNLO+NNLL in QCD [10], aswell as ggF cross section calculations that attempt togo beyond NNLO, including the recently completed fullN LO prediction. Details about the various predictionsare presented in Table XX, and the central values and abreakdown of the uncertainties of the calculations as wellas the measurement are reported in Table XXI.

Four of the predictions apply both electroweak cor-rections and consider finite b - and c -quark masses. Thesecorrections have non-negligible impacts on the ggF crosssection; the electroweak correction results in an increaseof approximately 5%, while the bottom and charm cor-rections give a O (5 − µ = m H as their overall scale, whiledFMMV and ADDFGHLM use µ = m H / Compatibility between predictions and data

Non-perturbative correction factors
Table XXIV presents multiplicative non-perturbativecorrection factors and associated uncertainties that areapplied to correct analytical parton-level predictions pre-sented in this Letter to particle level. These correctionsaccount for hadronization and multiple parton interac-tions, and are derived based on a number of underlyingevent and showering tunes applied to the Higgs bosonproduction MC samples used in the analysis.
