The production of pairs of Z bosons at the LHC is of great interest since it provides an excellent opportunity to test the predictions of the electroweak sector of the stan-dard model at the TeV energy scale; moreover it is the irreducible background to the search for the Higgs boson in the H ! ZZ decay channel. In the standard model, ZZ production proceeds at leading order (LO) via t-channel quark-antiquark interactions; the ZZZ and ZZ neutral triple gauge boson couplings (nTGCs) are absent; hence there is no contribution froms-channel q q annihilation at tree level. At the one-loop level, fermion triangles generate nTGCs ofOð104Þ [1]. Many models of physics beyond the standard model predict values of nTGCs at the level of 104to 103 [2]. The signature of nonzero nTGCs is an increase of theZZ cross section at high ZZ invariant mass and high transverse momentum of the Z bosons [3]. ZZ production has been studied in eþe collisions at LEP [4,5] and inp p collisions at the Tevatron [6,7]. No devia-tion of the measured cross secdevia-tion from the standard model expectation has been observed, and limits on anomalous nTGCs have been set [5,6].
This Letter presents the first measurement of ZZ [8] production in proton-proton collisions at a center-of-mass energypffiffiffisof 7 TeV, and limits on the anomalous nTGCs. The cross section for on-shell ZZ production (i.e., in the zero-width approximation) is predicted at next-to-leading order (NLO) in QCD to be 6:5þ0:30:2 pb [9]; this includes a 6% contribution from gluon fusion. Candidate ZZ events are reconstructed in theZZ ! ‘þ‘‘þ‘decay channel,
where‘ can be an electron or muon. Although this channel constitutes only 0:5% of the total ZZ cross section, its final state with four high transverse-momentum, isolated leptons has a very high expected signal to background ratio of30.
To reduce systematic uncertainties, the cross section is measured within a phase-space that corresponds closely to the experimental acceptance; this is termed the ‘‘fiducial’’ cross section. The fiducial phase-space definition requires the invariant mass of both lepton pairs to be between 66 and 116 GeV and all four leptons to be within the pseudor-apidity [10] rangejj < 2:5 and have transverse momen-tum pT> 15 GeV. The four-momenta of all photons present after the simulation of the parton shower which are within R pffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffi2þ 2< 0:1 of a lepton are summed into the four-momentum of that lepton. The total ZZ cross section in the on-shell approximation is obtained from the fiducial cross section using the knownZ ! ‘þ‘ branching ratio and a correction factor for the kinematic and geometrical acceptance.
Anomalous nTGCs for on-shell ZZ production can be parametrized by two CP-violating (fV4) and two CP-conserving (fV
5) complex parameters (V ¼ Z, )
which are zero in the standard model [3]. To ensure partial-wave unitarity, a form-factor parametrization is introduced to cause the couplings to vanish at high parton center-of-mass energypffiffiffis^:fiV ¼ fi0V=ð1 þ ^s=2Þn. Here,
is the energy scale at which physics beyond the standard model will be directly observable, fVi0 are the low-energy approximations of the couplings, and n is the form-factor power. Following Ref. [3], n ¼ 3 and ¼ 2 TeV are chosen, so that expected limits are within the values pro-vided by unitarity at LHC energies. The results with energy cutoff ¼ 1 are also presented as a comparison in the unitarity violation scheme.

The ATLAS detector [11] consists of inner tracking devices surrounded by a superconducting solenoid, elec-tromagnetic and hadronic calorimeters, and a muon spec-trometer with a toroidal magnetic field. The inner detector, in combination with the 2 T field from the solenoid, provides precision tracking of charged particles forjj < 2:5. It consists of a silicon pixel detector, a silicon strip detector, and a straw tube tracker that also provides tran-sition radiation measurements for electron identification. The calorimeter system covers the pseudorapidity range jj < 4:9. It is composed of sampling calorimeters with either liquid argon or scintillating tiles as the active media. In the region jj < 2:5 the electromagnetic liquid argon calorimeter is finely segmented and plays an important role in electron identification. The muon spectrometer has sepa-rate trigger and high-precision tracking chambers which provide muon identification and measurement injj < 2:7. A three-level trigger system selects events to be re-corded for offline analysis. The events used in this analysis were selected with single-lepton triggers with nominal transverse-momentum thresholds of 20 GeV for electrons and 18 GeV for muons. The efficiencies of the single-lepton triggers have been determined as a function of lepton pT using large samples of Z ! ‘þ‘ events. The trigger efficiency for events passing the offline selection described below is 99.9% with an uncertainty of 0.1%.
This measurement uses a data sample of proton-proton collisions atpffiffiffis¼ 7 TeV recorded between February and June 2011. After data quality requirements, the total inte-grated luminosity used in the analysis is 1:02 fb1. The integrated luminosity uncertainty is 3.7% [12].
Events are required to contain a primary vertex formed from at least three associated tracks. The vertex with the largest sum of thep2
Tcomputed from the associated tracks
is selected as the primary vertex.
Signal events are characterized by four high-pT, isolated
electrons or muons, in three channels: eþeeþe, þþ, and eþeþ. Lepton candidates are
required to be consistent with originating from the primary vertex. Muons are identified by matching tracks (or track segments) reconstructed in the muon spectrometer to tracks reconstructed in the inner detector [13]. Their mo-mentum is calculated by combining the information from the two systems and correcting for the energy deposited in the calorimeters. Only muons with pT> 15 GeV and jj < 2:5 are considered. In order to reject muons from the decay of heavy quarks, isolated muons are selected by requiring the scalar sum of the transverse momenta (pT)
of other tracks with pT> 1 GeV inside a cone of size R ¼ 0:2 around the muon to be no more than 15% of the muon pT. The overall reconstruction, identification, and isolation efficiency, measured in data using a large sample ofZ ! þ events, varies as a function ofpT from 92% at 15 GeV to 95% at 45 GeV.
Electrons are reconstructed from a cluster in the elec-tromagnetic calorimeter matched to a track in the inner detector [13]. Electron candidates are required to pass the ‘‘medium’’ identification criteria described in Ref. [13], to have a transverse momentum (measured in the calorimeter) of at least 15 GeV, and have a pseudorapidity of jj < 2:47. They must be isolated, using the same criterion as for muons, calculating the pT around the electron track.
Electron candidates within R ¼ 0:1 of any selected muon are rejected, and if two electron candidates are within R ¼ 0:1 of each other the one with the lower pT
is rejected. The overall reconstruction, identification, and isolation efficiency varies as a function ofpTfrom 63% at 15 GeV to 81% at 45 GeV.
Selected events are required to have exactly four leptons, and to have passed a single-muon or single-electron trig-ger. To ensure high trigger efficiency, at least one of these leptons must have pT> 20 GeV (25 GeV) for a muon (electron) and match to a muon (electron) reconstructed online by the trigger system within R< 0.1 (0.15).
Same-flavor, oppositely-charged lepton pairs are com-bined to form Z candidates. An event must contain two such pairs. In theeþeeþeandþþchannels, ambiguities are resolved by choosing the pairing which results in the smaller value of the sum of the twojm‘þ‘
mZj values. Figure 1 shows the correlation between the
invariant mass of the leading (higherpT) and the sublead-ing (lowerpT) lepton pair. The events cluster in the region where both masses are aroundmZ. Events are required to contain twoZ candidates with invariant masses satisfying 66 GeV < m‘þ‘< 116 GeV.

The reconstruction efficiency for ZZ events is deter-mined from a detailed Monte Carlo simulation. The LO generatorPYTHIA[14] with theMRSTmodified LO parton density function (PDF) set [15] is used to model pp ! ZZ ! ‘þ‘‘þ‘ events, where ‘ includes electrons,
muons, and leptons. The PYTHIA simulation includes the interference terms between the Z and diagrams; the mass threshold for the Z= boson is set to 12 GeV. The detector response is simulated [16] with a program based onGEANT4[17]. Additional inelasticpp events are included in the simulation, distributed so as to reproduce the number of collisions per bunch crossing in the data. The simulation is also corrected with scale factors, and the lepton momentum resolution adjusted, to reproduce the lepton reconstruction and identification efficiencies mea-sured in data.
The overall efficiencies of the reconstruction and selec-tion criteria for events generated within the fiducial phase space are ð40 3Þ%, ð79 2Þ%, and ð57 2Þ% for eþeeþe,þþ, andeþeþ, respectively.
The dominant systematic uncertainties arise from electron identification (6.6% in theeþeeþe final state, 3.1% in theeþeþfinal state) and from the muon reconstruc-tion efficiency (2.0% in þþ and 1.0% in eþeþ).
Background to theZZ signal originates from events with aZ (or W) boson decaying to leptons plus additional jets or photons (W=Z þ X), from top-quark production and from other diboson final states. Such events may contain electrons or muons from the decay of heavy-flavored had-rons, or muons from in-flight decay of pions and kaons; jets or photons may be misidentified as electrons. The majority of these background leptons are rejected by the isolation requirement.
To estimate the background contribution from four-lepton events in which one four-lepton originates from a jet, a sample of events containing three leptons passing all se-lection criteria plus one ‘‘leptonlike jet’’ is identified; such events are denoted‘‘‘j. For muons, the leptonlike jets are muon candidates that fail the isolation requirement. For electrons, the leptonlike jets are clusters in the electromag-netic calorimeter matched to inner detector tracks that fail either or both of the full electron selection and the isolation requirement. The events are otherwise required to pass the full event selection, treating the leptonlike jet as if it were a fully identified lepton. This event sample is dominated by Z þ X events. The background is then estimated by scaling this control sample by a measured factor f which is the ratio of the probability for a jet to satisfy the full lepton criteria to the probability to satisfy the leptonlike jet crite-ria. The background in which two selected leptons origi-nate from jets is treated similarly, by identifying a data sample with two leptons and two leptonlike jets; such events are denoted‘‘jj. To avoid double counting in the background estimate, and to take into account the expected
ZZ contribution in the control region, NðZZÞ, the total number of background eventsNðBGÞ is calculated as:
NðBGÞ ¼ Nð‘‘‘jÞf Nð‘‘jjÞf2 NðZZÞ: (1)
The factorf is measured in a sample of data selected with single-lepton triggers with criteria applied to suppress isolated leptons from W and Z bosons, and corrected for the remaining small contribution of true leptons using simulation. It is measured independently in and pTand the values combined assuming they are uncorrelated. A similar analysis is performed on Monte Carlo simulations of background processes; the larger of the statistical un-certainty onf determined from the data and the difference between data and simulation is taken as the systematic uncertainty in eachpT(or) bin. This results in a system-atic uncertainty which varies as a function ofpTfrom 57% (85%) at 15 GeV to 55% (77%) at 45 GeV for electrons (muons).
The numbers of expected and observed events after applying all selection criteria are shown in Table I. The expected number of signal events is determined from the PYTHIA simulation normalized to the NLO calculation using MCFM [9] with the MSTW2008 [18] NLO PDF set. The normalization factor, calculated within the phase-space of the fiducial cross section measurement, is 1.41. The expected numbers of signal events include contribu-tions of 1.6% from ZZ ! ‘þ‘‘þ‘ events generated outside the fiducial phase space and 0.3% from events where one of the Z bosons decays to leptons. Twelve ZZ candidates are observed in data, with a background expectation of 0:3 0:3ðstatÞþ0:40:3ðsystÞ, corresponding to a p value of 107 equivalent to a one-sided Gaussian
sig-nificance of 5. In the four-muon channel, 8 events are observed where 3:3þ0:40:3 signal plus background events are
expected. The probability of the expected number fluctuat-ing up to 8 or more is 3.2%.
The transverse-momentum distribution and the invariant mass distribution of the combined four-lepton system for the selected candidates are shown in Fig.2.

where ‘þ‘‘þ‘ refers to the sum of the eþeeþe, eþeþ, andþþfinal states. The total cross
section is determined similarly, correcting for the known Z ! ‘þ‘ branching ratios and the acceptance of the
fiducial phase space. This acceptance, calculated at NLO using MCFM version 6.0 with the MSTW2008 PDF set, is 0:507 0:009, where the error arises primarily from PDF uncertainties with a 1% contribution from QED radiative corrections and off-shell Z= effects evaluated from POWHEG BOX [19].

The result is consistent within errors with the NLO standard model total cross section for this process of 6:5þ0:30:2 pb [9]. Limits on anomalous nTGCs are determined using the total number of observed events only. TheZZ production
yield dependency on couplings is parametrized using fully simulated events generated withSHERPA[20] subsequently reweighted using the leading-order matrix element [3] within the framework of Ref. [21]. The reweighting pro-cedure uses simulated samples with standard model as well as non-standard-model coupling values to ensure adequate coverage of all kinematic regions. One dimensional 95% confidence intervals for the anomalous nTGCs are deter-mined using a maximum profile likelihood fit to the ob-served number of events. The systematic errors are included as nuisance parameters. The resulting limits for each coupling, determined assuming real couplings and with the other couplings fixed at their standard model value, are listed in TableII. The present results are domi-nated by statistical uncertainties: limits derived using sta-tistical uncertainties alone differ from those in TableIIby less than 0.01. These limits are comparable with, or are more stringent than, those derived from measurements at LEP [5] and the Tevatron [6]; it should be noted that limits from LEP do not use a form factor, and those from the Tevatron use ¼ 1:2 TeV.
