A search for the weak production of charginos and neutralinos decaying to a final state with three leptons (electrons or muons) and missing transverse momentum is presented. The analysis uses2:06 fb1 ofpffiffiffis¼ 7 TeV proton-proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with standard model expectations in two signal regions that are either depleted or enriched in Z-boson decays. Upper limits at 95% confidence level are set in R-parity conserving phenomenological minimal supersymmetric and simplified models. For the simplified models, degenerate lightest chargino and next-to-lightest neutralino masses up to 300 GeV are excluded for mass differences from the lightest neutralino up to 300 GeV.

Supersymmetric (SUSY) extensions [1–9] of the stan-dard model (SM) naturally address the gauge hierarchy problem [10–12] by postulating the existence of SUSY particles, or ‘‘sparticles’’, with spin differing by one-half unit with respect to that of their SM partner. If R-parity [13–17] is conserved, sparticles can only be pair-produced and will eventually decay into SM particles and the lightest SUSY particle (LSP) which is stable. Charginos (~i , i ¼ 1, 2) and neutralinos ( ~0j, j ¼ 1, 2, 3, 4) are the mass eigenstates formed from the linear superposition of the SUSY partners of the Higgs and electroweak gauge bo-sons. These are the Higgsinos, and the winos, zino, and bino, collectively known as gauginos. Naturalness requires
~
i and~0j(and third-generation sparticles) to have masses
in the hundreds of GeV range [18]. In scenarios where first and second generation sfermion masses are larger than few TeVs, the direct production of weak gauginos may be the dominant SUSY process at the Large Hadron Collider (LHC).
Leptonic decays of charginos include sneutrinos (~‘), sleptons ( ~‘) or W bosons (WðÞ~01), while those of unstable neutralinos include sleptons (‘~‘) or Z bosons (ZðÞ~01). When both gauginos decay leptonically, a dis-tinctive signature with three leptons and significant missing transverse momentum can be observed, the latter originat-ing from the two undetected LSPs and the neutrinos.
This Letter presents the first search with the ATLAS detector for the weak production of charginos and neutra-linos decaying to a final state with three leptons (electrons or muons) and missing transverse momentum. The analysis
is based on 2:06 fb1 of proton-proton collision data de-livered by the LHC at a center-of-mass energy pffiffiffis¼ 7 TeV between March and August 2011. The search sig-nificantly extends the current mass limits on charginos and neutralinos [19–22] and yields sensitivity in the mass region preferred by naturalness.
In this analysis, observations are interpreted in the phe-nomenological minimal supersymmetric SM (pMSSM [23]) and in simplified models [24]. In the pMSSM the masses of the ~i and~0jdepend on the gaugino masses M1
and M2, the Higgs mass parameterjj, and tan, the ratio
of the expectation values of the two Higgs doublets. The masses of the gluinos, squarks and left-handed sleptons are chosen to be larger than 1 TeV, while the right-handed sleptons (including third-generation ones) are assumed to be degenerate with m~‘R ¼ ðm~0
2þ m~01Þ=2. In these
scenar-ios, decays to sleptons are favored. In the simplified mod-els, the masses of the relevant particles (mass degenerate winolike ~1 and ~02; binolike ~01; ~; ~‘L) are the only free parameters of the theory. The ~1 and ~02 are produced via the s-channel exchange of a virtual gauge boson and decay via left-handed sleptons, including staus, and sneutrinos of mass m~¼ m~‘L ¼ ðm~01þ m~1Þ=2) with a branching ratio
of 50% each.
ATLAS [25] is a multipurpose particle detector with forward-backward symmetric cylindrical geometry. It in-cludes an inner tracker (ID) immersed in a 2 T magnetic field providing precision tracking of charged particles for pseudorapiditiesjj < 2:5 [26]. Calorimeter systems with either liquid argon or scintillating tiles as the active media provide energy measurements over the range jj < 4:9. The muon detectors outside the calorimeters are contained in a toroidal magnetic field produced by air-core super-conducting magnets with field integrals varying from 1 to 8 T m. They provide trigger and high-precision tracking capabilities for jj < 2:4 and jj < 2:7, respectively.

Electrons must satisfy tight identification criteria and fulfil jj < 2:47 and ET> 10 GeV, where jj and ET are
de-termined from the calibrated clustered energy deposits in the electromagnetic calorimeter matched to an ID track. Muons are reconstructed by combining tracks in the ID and tracks in the muon spectrometer [27]. Reconstructed muons are considered as candidates if they have transverse momentum pT> 10 GeV, jj < 2:4, and transverse
im-pact parameter with respect to the primary vertexjd0j < 0:2 mm. ‘‘Tagged’’ leptons are electrons and muons, well separated from each other and from candidate jets. ‘‘Signal’’ leptons are tagged leptons for which the scalar sum of the tracks’ transverse momenta withinffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffi R

p
< 0:2 around the lepton candidate is less than 10% of the ET for electrons, and less than
1.8 GeV for muons. Jets are reconstructed from clustered energy deposits calibrated at the electromagnetic scale using the anti-ktalgorithm[28] with a radius parameter of
0.4. The jet energy is corrected to account for the non-compensating nature of the calorimeter using correction factors obtained from Monte Carlo (MC) simulation and parameterized as a function of the jet ETand [29]. Jets
considered in this analysis have ET> 20 GeV and jj <
2:8. Jets are identified as containing a b-quark, and thus called ‘‘b-tagged’’, using a multivariate technique based on quantities such as the impact parameter of the tracks associated to the secondary vertex, tracks in jet and other jet shape information, consistent with the expected topol-ogy of b-quark decays. The b-tagging algorithm [30] cor-rectly identifies b-quark jets in top decays with an efficiency of 60% and misidentifies jets containing light-flavor quarks and gluons with a rate of <1%, for jets with jj < 2:5 and jet ET> 20 GeV. The missing transverse
momentum, EmissT , is the magnitude of the vector sum of the
transverse momentum or transverse energy of all pT>
10 GeV muons, ET> 10 GeV electrons, ET> 20 GeV
jets, and calibrated calorimeter clusters with jj < 4:5 not associated to these objects [31].
Several MC generators are used to simulate SM pro-cesses and SUSY signals relevant for this analysis.HERWIG
[32] is used to simulate diboson processes (WWðÞ, ZZðÞ, WZðÞ), whileMADGRAPH [33] is used for the ttWðÞ=ZðÞ processes. MC@NLO [34] is chosen for the simulation of single and pair production of top quarks, while ALPGEN
[35] is used to simulate WðÞ=ZðÞþ jets. Expected diboson yields are normalized using next-to-leading order (NLO) QCD predictions obtained with MCFM [36,37]. The top-quark pair-production contribution is normalized to approximate next-to-next-to-leading (NNLO) order calcu-lations [38] and the ttWðÞ=ZðÞ contributions are normal-ized to NLO results [39]. The QCD NNLOFEWZ[40,41] andMCFMcross-sections are used for NNLO normalization of the Z þ light-flavor jets and Z þ heavy-flavor jets processes, respectively. The choice of the parton distribu-tion funcdistribu-tions (PDFs) depends on the generator. MRST
2007 LO* [42] sets are used for HERWIG, CTEQ6L1 [43]
with MADGRAPH and ALPGEN, and CTEQ6.6 [44] with
MC@NLO. The pMSSM and simplified model samples are produced with HERWIG and HERWIG++[45], respectively, and the yields are normalized to the NLO cross-sections obtained from PROSPINO [46] using the PDF set CTEQ6.6
with the renormalization/factorization scales set to the average of the relevant gaugino masses. Fragmentation and hadronization for the ALPGEN and MC@NLO
(MADGRAPH) samples are performed with HERWIG
(PYTHIA [47]). For all MC samples, the propagation of particles through the ATLAS detector is modeled using
GEANT4[48,49]. The effect of multiple proton-proton col-lisions from the same or different bunch crossings is in-corporated into the simulation by overlaying additional minimum bias events onto hard scatter events using
PYTHIA. Simulated events are weighted to match the
dis-tribution of the mean number of interactions per bunch crossing observed in data.
The data sample was collected with a single-muon trig-ger (pT> 18 GeV) or a single-electron trigger (ET> 20 or
22 GeV, depending on the instantaneous luminosity). At least one signal lepton is required to have triggered the event and have pTðETÞ above 20 GeV (25 GeV) for muons
(electrons). Events recorded during normal running con-ditions are analyzed if at least one of the reconstructed primary vertices has more than four tracks associated to it. Events containing jets withjj < 4:9 and failing the qual-ity criteria described in Ref. [29] are rejected to suppress both collisional and noncollisional background. Selected events must contain exactly three signal leptons. As lep-tonic decays of ~0jyield same-flavor opposite-sign (SFOS) lepton pairs, the presence of at least one such pair is required. The invariant mass of any SFOS lepton pair must be above 20 GeV to suppress background from low mass resonances and the missing transverse momentum must satisfy EmissT > 50 GeV.
Two signal regions are then defined: a ‘‘Z-depleted’’ region (SR1), with no SFOS pairs having invariant mass within 10 GeV of the nominal Z-boson mass; and a ‘‘Z-enriched’’ one (SR2), where at least one SFOS pair has an invariant mass within 10 GeV of the Z-boson mass. Events in SR1 are further required to contain no b-tagged jets to suppress contributions from b-jet-rich backgrounds, where a fake lepton could originate from a heavy-flavor decay. The SR1 and SR2 selections target SUSY events with intermediate slepton or on-mass-shell Z-boson de-cays, respectively.
Several SM processes contribute to the background in SR1 and SR2. A background process is considered ‘‘irre-ducible’’ if it leads to events with three real and isolated leptons, referred to as ‘‘real’’ leptons below. These include diboson (WZðÞand ZZðÞ) and ttW=ZðÞproduction, where the gauge boson may be produced off-mass-shell. Their contribution is determined using the corresponding MC
samples, for which lepton and jet selection efficiencies are corrected to account for differences with respect to data. A ‘‘reducible’’ process has at least one ‘‘fake’’ object, that is either a lepton from a semileptonic decay of a heavy-flavor quark or an electron from an isolated photon conversion. The contribution from misidentified light-flavor quarks is negligible. The reducible background includes single- and pair-production of top-quark and WWðÞor WðÞ=ZðÞ pro-duced in association with jets or photons. The dominant component is the production of top quarks, with a contri-bution of 1% or less from ZðÞþ jets production. The reducible background is estimated using a ‘‘matrix method’’ similar to that described in Ref. [50].
In this implementation of the matrix method, the signal lepton with the highest pTor ETis taken to be real, which
is a valid assumption in 99% of the cases, based on MC studies. The number of observed events with one or two fakes is then extracted from a system of linear equations linking the number of events with two additional signal or tagged candidates to the number of events with two addi-tional candidates that are either real or fake. The coeffi-cients of the linear equations are functions of the real lepton identification efficiencies and of the fake object misidentification probabilities. The identification effi-ciency is measured in data using lepton candidates from Z ! ‘‘ decays.
Misidentification probabilities for each fake type (heavy-flavor, conversion) and for each reducible back-ground process are obtained using simulated events with one signal and two tagged leptons. These misidentification probabilities are then corrected using the ratio (fake scale factor) of the misidentification probability in data and that in MC simulation obtained in dedicated control samples. For heavy-flavor fakes, the correction factor is measured in b b events, while for conversion fakes it is determined in a sample of photons radiated from a muon in Z ! decays. A weighted average misidentification probability is then calculated by weighting the corrected type- and process-dependent misidentification probabilities accord-ing to the process cross section.
An additional source of background is due to events with two signal leptons and one virtual photon converting into two muons, one with pT above 10 GeV. The contribution
from events in which both muons from the virtual photons have pTabove 10 GeV is negligible due to the requirement
on the dilepton pair invariant mass. For events with only one muon above threshold, an upper limit of0:5 0:5 in SR1 and of 0:7 0:7 in SR2 is obtained from data as follows. The number of observed events with exactly two signal leptons and EmissT > 50 GeV is rescaled by the probability that any of the signal leptons could have radi-ated the converted photon. This probability is measured in events with EmissT < 50 GeV as the ratio of number of
events with three signal muons with trilepton invariant mass within 10 GeV of the nominal Z boson mass to the
number of events with two signal muons having the dilep-ton mass in the same mass window.
The matrix method has been tested using MC events and shown to be accurate within 2%. The background predic-tions have been validated in a region dominated by ZðÞþ jets production (VR1: three signal leptons, 30 < EmissT < 50 GeV) and in one dominated by top pair-production (VR2: three signal leptons, SFOS lepton pairs vetoed, EmissT > 50 GeV). The data and predictions are in agree-ment within the quoted statistical and systematic uncer-tainties as shown in TableI.
Several sources of systematic uncertainty are considered in the signal regions. The systematic uncertainties affecting the MC based estimates (irreducible background yield, misidentification probabilities, signal yield) include the theoretical cross-section uncertainty due to scale and PDFs, the acceptance uncertainty due to PDFs, jet energy scale, jet energy resolution, lepton energy scale, lepton energy resolution, lepton efficiency, b-tagging efficiency, event quality selection, and the uncertainty on the lumi-nosity. In SR1, the total uncertainty on the irreducible background is 17%. This includes the uncertainty on the acceptance due to PDFs (14%), that on the theoretical cross section due to scale and PDFs (7%), and that from the limited number of simulated events (10%), while all the remaining uncertainties on the irreducible background in this signal region range between 0.5%–5%. The total un-certainty on the reducible background is 29%. This in-cludes an uncertainty on the object misidentification probability of 10%–30% from the sources listed above. The uncertainty from the dependence of the misidentifica-tion probability on EmissT (0.4%–17%) and the uncertainty on the fake scale factors (10%–50%) are also included in the total, together with the uncertainty from the limited number of data events with three tagged leptons, of which at least one is a signal lepton. The total uncertainties on the signal cross-section range between 10%–15%. These in-clude uncertainties due to the renormalization and factori-zation scale, S, and PDFs. The maximum uncertainty
obtained from either the CTEQ6.6 or the MSTW[51] PDF set is used. In SR2, the values of systematic uncertainties are similar to those obtained in SR1. The only exceptions

are the uncertainty from the limited number of simulated events (4%) and the uncertainty on the reducible back-ground (52%). In all of the above, the value used for the uncertainty on the luminosity is 3.7%.
The numbers of observed events and the prediction for SM backgrounds in SR1 and SR2 are reported in TableI. The probability that the background fluctuates to the ob-served number of events or higher is calculated in the frequentist approach and found to be 19% in SR1 and 6% in SR2. The distributions of the EmissT in the two signal regions are presented in Fig.1. The yield in SR1 for one of the simplified model scenarios (m~
1, m~02, m~‘L, m~01 ¼
250, 250, 175, 100 GeV) is also shown for illustration purposes.
No significant excess of events is found in either signal region. Upper limits on the visible production cross-section of 9.9 fb in SR1 and 23.8 fb in SR2 are placed at 95% confidence level (C.L.) with the modified frequentistC:L:s prescription [52]. No corrections for the effects of experi-mental resolution, acceptance and efficiency are applied. All systematic uncertainties and their correlations are taken into account via nuisance parameters. The corre-sponding expected limits are 7.1 and 14.1 fb, respectively. In SR2, the observed limit on the visible cross-section is less stringent than the expected limit because of the up-wards fluctuation in the number of events in data with respect to the expected background. SR1 provides better sensitivity in the parameter space considered and the limits are interpreted in simplified models and pMSSM scenarios with M1¼ 100 GeV and tan ¼ 6 (Fig. 2). The chosen
M1value leads to a sizable mass splitting between ~1 and
~0
1 and therefore to a large acceptance. The value oftan
does not have a significant impact on ðpp ! ~i ~0jÞ
BRð ~i ~0j ! ‘‘‘~01Þ, which varies by 10% if tan is raised to 10.
In the simplified models, degenerate ~1 and ~02 masses up to 300 GeV are excluded for large mass differences from the ~01. Care has to be taken when interpreting the simpli-fied model limit in the context of a pMSSM scenario, where the mass of the sneutrino is lighter than the mass of the left-handed slepton, leading to higher lepton mo-menta from chargino decays and to a change in the branch-ing ratios of the ~02.
In summary, results from the first ATLAS search for the weak production of charginos and neutralinos decaying to a final state with three leptons (electrons or muons) and missing transverse momentum are reported. The analysis is based on 2:06 fb1 of proton-proton collision data deliv-ered by the LHC atpffiffiffis¼ 7 TeV. No significant excess of events is found in data, where upwards fluctuations of less than 2-sigma are observed. The null result is interpreted in pMSSM and in simplified models. For the simplified mod-els with intermediate sleptons considered in this paper, degenerate lightest chargino and next-to-lightest neutralino masses are excluded up to 300 GeV for mass differences to the lightest neutralino up to 300 GeV.
