Abstract
A fiducial cross section for Wγ production in proton-proton collisions is measured ata center-of-mass energy of 13 TeV in 137 fb−1 of data collected using the CMS detectorat the LHC. The W → eν and µν decay modes are used in a maximum-likelihood fitto the lepton-photon invariant mass distribution to extract the combined cross sec-tion. The measured cross section is compared with theoretical expectations at next-to-leading order in quantum chromodynamics. In addition, 95% confidence level in-tervals are reported for anomalous triple-gauge couplings within the framework ofeffective field theory.
The associated production of a W boson and a photon in proton-proton (pp) collisions cor-responds to a fundamental process that has bearing on the basic ingredients of the standardmodel (SM). A precise measurement of the pp → Wγ cross section probes the WWγ triple-gauge coupling (TGC) and higher-order corrections to it. The structure and strength of theWWγ TGC are closely related to the SU(2)×U(1) gauge symmetry of the SM and the mech-anism for its breaking, which can be altered through the presence of new physics with al-ternative symmetries or symmetry-breaking mechanisms, such as composite W models [1].Physics at high energy scale can be described in a generic way in the framework of effectivefield theory (EFT), and the pp → Wγ production cross section has direct implications for thelowest-dimension operators in the EFT expansion, including OWWW = Tr[WµνWνρWµ
ρ ], whichdirectly affects the WWγ TGC [2]. Previous measurements of Wγ production from the LHCuse the data collected in 2011 at a center-of-mass energy of 7 TeV [3, 4]. Here we report thefirst measurement of the pp →Wγ cross section at 13 TeV based on data collected by the CMSexperiment in 2016–2018, corresponding to an integrated luminosity of 137 fb−1.
At leading order in quantum chromodynamics (QCD), `+ν`γ and `−ν`γ (where ` = e/µ) pro-duction in pp collisions with an s-channel W boson can proceed through initial-state radiation(ISR) from one of the incoming quarks, final-state radiation (FSR) from the outgoing chargedlepton, or the WWγ TGC vertex shown in Fig. 1. At higher orders in QCD, additional quarkscan appear in the final state, and the photon can arise by FSR from an outgoing quark or lepton.

The central feature of the CMS apparatus is a superconducting solenoid of 6 m internal di-ameter, providing a magnetic field of 3.8 T. A silicon pixel and strip tracker, a lead tungstatecrystal electromagnetic calorimeter (ECAL), and a brass and scintillator hadron calorimeter,each composed of a barrel and two end sections, are located within the magnetic field of thesolenoid. Forward calorimeters extend the pseudorapidity (η) coverage provided by the bar-rel and end detectors. Muons are measured using in gas-ionization chambers, including drifttubes, cathode strip chambers, and resistive plate chambers, embedded in the steel flux-returnyoke outside the solenoid. A more detailed description of the CMS detector, as well as thedefinition of the coordinate system and the relevant kinematic variables, is reported in Ref. [5].
Electrons and photons are measured in the range |η| < 2.5 defined by the tracker acceptance.The energy of electrons is a combination of three measurements: the electron momentum atthe primary interaction vertex as determined by the tracker [6]), the energy of the correspond-ing ECAL cluster, and the energy sum of all bremsstrahlung photons spatially compatible withoriginating from the electron track. The photon momentum is determined solely using the en-ergy measurement in the ECAL. The photon’s ECAL cluster is required to be inconsistent witha charged-particle track reconstructed in the tracker [7]. Muons are measured in the pseudora-pidity range |η| < 2.4 and their momenta are determined using a global fit of muon measure-
2
ments in the gas-ionization chambers and matched tracks in the silicon tracker [8].
The missing transverse momentum vector ~pmissT is computed as the negative vector pT sum of
all measured particles in an event, reconstructed with the particle flow algorithm [9], and itsmagnitude is denoted by pmiss
T [10]. The ~pmissT of an event is intended to represent the neutrinos
associated with a single pp interaction within a bunch crossing. The contribution to~pmissT due to
particles from additional pp interactions within the same bunch crossing (pileup) is mitigatedthrough the pileup-per-particle identification algorithm [11, 12]. The ~pmiss
T is also modified toinclude corrections to the energy scale and resolution of the reconstructed jets in the event.
The Wγ production cross section has been calculated with next-to-leading-order (NLO) QCDcorrections at fixed order matched to parton shower [13, 14], with NLO electroweak correctionsat fixed order [15], and with next-to-next-to-leading-order (NNLO) QCD corrections at fixedorder [16–18]. For an inclusive cross section, the NLO QCD corrections are large and positive,more than 100% compared to the LO prediction, whereas the NLO electroweak corrections arenegligible compared to experimental precision. The NNLO QCD corrections are positive and20–30% relative to the NLO QCD prediction.
The signal processes pp → `+ν`γ and pp → `−ν`γ are simulated at NLO in QCD using MAD-GRAPH5 aMC@NLO version 5.2.6 [13] with up to one additional jet in the matrix element calcu-lation, merged with jets from the parton showering using the FxFx merging scheme [19]. Thesetwo processes are also simulated at NLO in QCD with POWHEG version 2.0 [14, 20–22] using theNLO competition option selected for handling the radiation of a photon or a jet from Born-levelW boson production with a jet. For both MADGRAPH5 aMC@NLO and POWHEG, the partonshowering and hadronization are performed using PYTHIA8 version 8.226 [23], and the detec-tor simulation is performed using GEANT4 [24]. To match data-taking conditions, we generatethree sets of events corresponding to 2016, 2017, and 2018. The PYTHIA8 CUETP8M1 [25] tunewith the NNPDF30 nlo nf 5 pdfas [26] parton distribution functions (PDF) are used for the2016 simulation, and the PYTHIA8 CP5 [27] tune with the NNPDF31 nnlo hessian pdfas [28]PDFs are used for the 2017 and 2018 simulations. The simulations include W → τντ decays,which are considered part of the signal when a τ decays with an emission of an electron or amuon. No EW or NNLO QCD corrections are applied.
We select W+γ → `+ν`γ and W−γ → `−ν`γ events from the set of events that pass a level-one [29] and a high-level [30] trigger that require a single muon or electron that is isolatedfrom other detector activity and is therefore likely to be promptly produced as opposed toproduced during the hadronization of a jet. The pT threshold of the high-level trigger leptonvaries between 24 and 32 GeV, depending on the year of data taking and the lepton flavor.We require the presence of a single high-quality [31] reconstructed photon, pmiss
T exceeding40 GeV, and that the isolated electron or muon satisfies additional quality criteria [8, 32]. Offlinekinematical requirements on the selected objects, based on the detector acceptance and thetrigger thresholds, are photon pT > 25 GeV, photon |η| < 2.5, electron (muon) |η| < 2.5 (2.4),electron (muon) pT > 30 (26) or > 35 (30) GeV, depending on the year of data taking. To reducethe background from Zγ events, we reject events that contain an additional muon or electron
with pT > 20 GeV that satisfies minimal quality criteria. Finally, ∆R =√(∆η)2 + (∆φ)2, where
∆φ and ∆η are the spatial separations in azimuthal angle φ (in radians) and η between thelepton and photon, is required to exceed 0.5.
The signal is defined as the Wγ process originating from a fiducial region defined with isolatedprompt photons and isolated prompt dressed (as defined below) leptons. A lepton or photonis considered isolated if the pT sum of all stable particles within ∆R = 0.4, divided by the pTof the lepton or photon, is less than 0.5. A lepton is considered prompt if it originates from the
3
hard process; a photon is considered prompt if it originates from the hard process or an FSR orISR process involving a particle that originates from the hard process. A lepton is dressed byadding to its four-momentum the four-momenta of all photons within ∆R = 0.1; this procedureis intended to restore the lepton to its pre-FSR state. The fiducial region requirements are:photon and lepton |η| < 2.5 and pT > 25 GeV, and ∆R(lepton,photon) > 0.5.
Background processes containing a prompt lepton and a prompt photon, including Zγ pro-duction, ttγ production, and VVγ (where V = W/Z) production are simulated using MAD-GRAPH5 aMC@NLO and PYTHIA8, in a manner similar to that for the signal samples. The back-ground due to photon conversions in the detector material that lead to reconstructed electronsis estimated with a simulated sample of γγ events made with Sherpa version 2.2.5[33]. Thebackground due to events containing nonprompt leptons and photons, including those frominstrumental mismeasurements and genuine leptons/photons within jets, is estimated fromdata. The ratio of well-isolated, high-quality leptons to less-well-isolated, lower-quality lep-tons is measured in a dijet control region in data as a function of the lepton |η| and pT, andcorrected for prompt leptons and prompt photon conversions based on simulated samples. Asimilar procedure is applied for photons based on a W+jets control region. In the nonpromptphoton case, a fit to the width of the photon ECAL shower is used to determine the nonpromptphoton fraction in the well-isolated, high-quality category, as described in Ref. [34]. The twoprocedures are combined in a way that avoids double counting to estimate the contributionfrom events containing both a nonprompt lepton and a nonprompt photon. The backgroundcontribution from events that contain a prompt lepton from the primary interaction and aprompt photon from a pileup interaction, mainly W+jets primary interaction events with γ+jetspileup interaction events, is estimated using simulated samples. Finally, the background fromelectron-induced photons, occurring when an electron track is misreconstructed in the trackeror not properly matched to the corresponding ECAL cluster, is estimated using a fit to them`γ distribution in data, which is sharply peaked because of the Z resonance, with a templateconstructed from simulation.
The observed distributions of m`γ are compared with the expected distributions based on theMADGRAPH5 aMC@NLO simulation in Fig. 2. The experimental data agrees with the predic-tion within uncertainties. The expected and observed numbers of events are listed in Table 1.
The signal strength is extracted from a binned maximum likelihood fit to the m`γ distribution,where the likelihood function is the product of a Poisson probability density functions for eachbin. A simultaneous fit of the electron and muon channels is used for our main results; in addi-tion, muon-channel-only and electron-channel-only fits are performed as a consistency check.In order to efficiently maximize the likelihood function with the large number of parametersthat we consider, we use a TENSORFLOW-based minimizer [35, 36]. The fit is performed in therange 10 to 250 GeV with 2 GeV bins. In the electron-channel-only fit and the simultaneous fit,the normalization of the electron-induced photon template is a free parameter in addition tothe Wγ normalization, whereas in the muon-channel-only fit, the normalization of the electron-induced photon template is constrained by a 100% log-normal uncertainty around its nominalvalue and the Wγ signal normalization is the only free parameter.
A variety of sources of systematic uncertainty are considered as nuisance parameters in the fitsubject to log-normal constraints. Experimental sources of systematic uncertainty include: thejet energy scale and resolution (which affect the~pmiss
T ), the lepton and photon identification effi-ciency, the integrated luminosity measurement, the statistical power of our simulated samplesand data control regions, and the nonprompt photon and nonprompt lepton background es-timation methods. Theoretical sources of systematic uncertainty include: the renormalization

The signal and background processes thatare drawn correspond to the estimates made before the fit, except that normalization of theelectron-induced photon (one of the free parameters) is scaled by 1.8 from its pre-fit value. Theuncertainty in the prediction (the hatched band) is the quadratic sum of the systematic uncer-tainties. The uncertainty in the data is statistical. The Wγ refers to the MADGRAPH5 aMC@NLO
simulation of Wγ events.
and factorization QCD scales, and PDFs. The renormalization and factorization QCD scales arevaried by a factor 2 up and down, excluding the (2,1/2) and (1/2,2) cases, and the envelopeof these variations is taken as the uncertainty. The systematic uncertainty due to the PDFs isthe standard deviation of the 32 members of the PDF4LHC15 nnlo 30 pdfas PDF set [26, 37–39]. The uncertainties in the photon identification efficiency (1–4%, depending on the photonpT and η) and the integrated luminosity measurement (1.8%) have the largest impact on themeasurement.
The theoretically predicted cross section is 15.4± 1.2 (scale)± 0.1 (PDF) pb based on the NLOQCD MADGRAPH5 aMC@NLO simulation and 22.4 ± 3.2 (scale) ± 0.1 (PDF) pb based on theNLO QCD POWHEG simulation with the NLO competition option, where scale refers to QCDscale.
The measured cross section from the simultaneous fit with the uncertainties divided into sta-tistical, experimental, and theoretical components is σ = 15.58± 0.75 pb = 15.58± 0.05 (stat)±0.73 (syst)± 0.15 (theo) pb. The measured cross section based only on the electron channel isσ = 15.09± 0.09 (stat)± 1.02 (syst)± 0.32 (theo) pb and the measured cross section based onlyon the muon channel is σ = 15.77± 0.06 (stat)± 0.88 (syst)± 0.12 (theo) pb.
Next we search for new physics that could result in anomalous contributions to the cross sectionat high mass scale Λ. We consider an EFT in which dimension-six operators are added to theSM [2]:
L = LSM + ∑i
ciΛ2Oi.

Table 1: Expected and observed numbers of events. The signal and background yields corre-spond to the estimates made before the fit, except that normalization of the electron-inducedphoton yield (one of the free parameters) is scaled by 1.8 from its pre-fit value. The un-certainty is the quadratic sum of the systematic uncertainties. The Wγ refers to the MAD-GRAPH5 aMC@NLO simulation of Wγ. The Wγ signal and Wγ nonfiducial are the contribu-tions to the signal region from the Wγ process originating from within and outside the fiducialregion, respectively.
The operators that are relevant to Wγ production are:
OWWW = Tr[WµνWνρWµρ ],
OB = (DµΦ)†Bµν(DνΦ),
OWWW = Tr[WµνWνρWµρ ], and
OW = (DµΦ)†Wµν(DνΦ),
where Wµν and Bµν are the SU(2)×U(1) field strength tensors, Φ is the Higgs field, and Wµν isdefined as εµνρσWρσ/2 (εµνρσ is totally antisymmetric with ε0123 = 1). The lowest dimensionCP-even operator that directly alters the WWγ TGC is OWWW . The photon pT distributionshown in Fig. 3 is used for the extraction of limits on the coefficients of these four operators.The NLO QCD reweighting feature of MADGRAPH5 aMC@NLO [40] is used to determine theyield of the Wγ signal as a function of each operator coefficient.
We compute expected and observed 95% confidence level limits on each operator coefficientbased on the profile likelihood ratio test statistic [41]. Each operator coefficient is scannedindependently with all other operator coefficients set to zero. In addition to the sources of sys-tematic uncertainties considered in the cross section fit, the 45% difference between the MAD-GRAPH5 aMC@NLO and POWHEG fiducial cross sections is assigned as an uncertainty in thenormalization of the SM component of the model. The observed and expected limits are listedin Table 2. The observed limits on cWWW/Λ2 are decreased by a factor of ≈ 1.75 relative tothe previous best result [42]. These limits can be converted through a linear relationship tolimits on the parameters λγ, λγ, and κγ in the Lagrangian approach to anomalous couplings,also known as the LEP parametrization, described in Ref. [2]. The expected limits on theseparameters are −0.0033 < λγ < 0.0033, −0.074 < κγ < 0.072, and −0.0016 < λγ < 0.0016,while the corresponding observed limits are−0.0035 < λγ < 0.0035,−0.066 < κγ < 0.065, and−0.0017 < λγ < 0.0017.

In summary, the cross section for pp →Wγ production has been measured at a center-of-massenergy of 13 TeV for the first time. The measured cross section in a defined fiducial regionis σ = 15.58 ± 0.05 (stat) ± 0.73 (syst) ± 0.15 (theo) pb = 15.58 ± 0.75 pb, consistent with theMADGRAPH5 aMC@NLO next-to-leading-order (NLO) quantum chromodynamics (QCD) pre-diction of σ = 15.4± 1.2 (scale)± 0.1 (PDF) pb, and less than the POWHEG NLO QCD with NLOcompetition prediction of σ = 22.4± 3.2 (scale)± 0.1 (PDF) pb. The cross sections in the elec-tron and muon channels are consistent with each other. The high tail of the photon transversemomentum distribution is used to set 95% confidence level limits on dimension-six effectivefield theory parameters, including the most stringent limit to date on the coefficient of OWWW ,the lowest dimension CP-even operator that directly alters the WWγ TGC.
