This Letter presents the first search for a heavy particle decaying into an e final state inpffiffiffis¼ 7 TeV pp collisions at the LHC. The data were recorded by the ATLAS detector during 2010 and correspond to a total integrated luminosity of35 pb1. No excess above the standard model background expectation is observed. Exclusions at 95% confidence level are placed on two representative models. In an R-parity violating supersymmetric model, tau sneutrinos with a mass below 0.75 TeV are excluded, assuming all R-parity violating couplings are zero except 0311¼ 0:11 and 312¼ 0:07. In a lepton flavor
violating model, a Z0-like vector boson with masses of 0.70–1.00 TeV and corresponding cross sections times branching ratios of 0.175–0.183 pb is excluded. These results extend to higher mass R-parity violating sneutrinos and lepton flavor violating Z’s than previous constraints from the Tevatron.

Events with e (e) in the final state, which played an important role in the discoveries of the tau lepton and the top quark, have a clean experimental signature and low background. Many new physics models allow an e sig-nature. For example, in R-parity violating (RPV) super-symmetric models [1] a sneutrino can decay to e. Models with additional gauge symmetry can accommodate an e signature through lepton flavor violating (LFV) decays of an extra gauge boson Z0 [2]. Standard model (SM) pro-cesses that can produce an e signature typically have small cross sections, and the e invariant mass (me) lies
below the range favored for new physics signals. This Letter reports a search for a heavy particle decaying into the e final state using data taken with the ATLAS detec-tor. The results are interpreted in terms of the production and decay of a tau sneutrino~and a Z0. Both the CDF and D0 Collaborations at the Tevatron collider have reported searches for the RPV production and decay of the~[3–7]. The CDF Collaboration has also set limits on the LFV couplings as a function of the Z0mass [4].
The ATLAS detector [8] is a multipurpose particle phys-ics apparatus with a forward-backward symmetric cylin-drical geometry and near4 coverage in solid angle [9]. The inner tracking detector (ID) consists of a silicon pixel detector, a silicon microstrip detector, and a transition radiation tracker. The ID is surrounded by a thin super-conducting solenoid providing a 2 T magnetic field and by a finely segmented, hermetic calorimeter. The latter covers jj < 4:9 and provides three-dimensional reconstruction
of particle showers using lead-liquid argon sampling for the electromagnetic compartment followed by a hadronic compartment which is based on iron-scintillating tiles sampling in the central region and on liquid argon sam-pling with copper or tungsten absorbers forjj > 1:7. The muon spectrometer surrounds the calorimeters and consists of three large superconducting toroids, a system of preci-sion tracking chambers, and detectors for triggering.
The data used in this analysis were recorded in 2010 at a center-of-mass energy pffiffiffis¼ 7 TeV. Application of data-quality requirements results in a total integrated luminosity of 35 pb1 with an estimated uncertainty of 11% [10]. Events are required to satisfy one of the single lepton (e or ) triggers, which have nominal transverse momentum pT thresholds up to 15 GeV for e and 13 GeV for . The
trigger efficiency is measured to be 100%, with a precision of 1%, for e candidates containing two leptons with transverse momentum pT> 20 GeV.
To select e events, the electron candidate is required to have pT> 20 GeV and to lie inside the pseudorapidity
regions jj < 1:37 or 1:52 < jj < 2:47. The event is re-jected if the candidate cluster is located in a problematic region of the electromagnetic calorimeter. Electron identi-fication and isolation requirements provide rejection against hadrons. A set of electron identification criteria based on the calorimeter shower shape, track quality, and track matching with the calorimeter cluster, referred to as ‘‘medium’’ in Ref. [11], is applied. In addition, a calorime-ter isolation cricalorime-terion ER<0:2T =ET< 0:1 is applied, where
ER<0:2T is defined as the transverse energy deposited in the calorimeter within a cone of radiusR¼pffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffi2þ2< 0:2 around the electron cluster, excluding the core energy deposited by the electron, and ET is the transverse energy
of the electron.
The muon candidate must be reconstructed in both the ID and the muon spectrometer. A good match of the

parameters of the ID and muon spectrometer tracks is required, and the pTvalues measured by these two systems
must be compatible. Furthermore, the muon candidate must have pT> 20 GeV, jj < 2:4, and be isolated in
the ID with pR<0:2T =pT< 0:1, where pR<0:2T is defined
as the sum of the pT of tracks with pT> 1 GeV within a
cone of radiusR < 0:2 around the muon track, excluding the muon track.
Jets are reconstructed by using the anti-ktjet clustering
algorithm [12] with a radius parameter of 0.4. Only jets with pT> 20 GeV and jj < 2:5 are considered. If such a
jet and an electron lie withinR ¼ 0:2 of each other, the jet is discarded. Leptons are considered only if they are separated from all of the remaining jets by R > 0:4. Electrons and muons are also required to be separated from each other byR > 0:2.
The e candidate events are required to have exactly one electron and one muon with opposite charge satisfying the above selection criteria. Furthermore, events have to contain at least one primary vertex reconstructed with more than four associated tracks with pT> 150 MeV.
The SM processes that can produce an e signature are predominantly tt, Z=! , W=Z þ jets, diboson, single top, and QCD multijet events. Among the processes listed above, tt, Z=! , single top, WW, WZ, and ZZ produce electrons and muons in the final state and amount to80% of the expected e data yield. The contributions from these processes are estimated by using Monte Carlo (MC) samples generated at pffiffiffis¼ 7 TeV and processed with the standard chain of the ATLASGEANT4[13] simu-lation and reconstruction [14] using the ATLAS MC09 parameter tune [15]. The event generators used are
PYTHIA 6.421 [16] (W and Z=), POWHEG 1.0 [17] (tt),
MADGRAPH 4 [18] (W=Z þ ), MC@NLO 3.4 [19] (single top), andHERWIG 6.510[20] (WW, WZ, and ZZ). The MC samples are normalized to cross sections with higher order corrections applied, as follows. The cross section is calcu-lated to next-to-next-to-leading-order accuracy for W and Z=[21], next-to-leading-order plus next-to-next-to-lead-ing-log for tt [22], and next-to-leading-order for WW, WZ, and ZZ [23]. Single top and W=Z þ cross sections come from MC@NLO and MADGRAPH, respectively. Studies of Z=! ‘‘ (‘ ¼ e; ) events have shown that the lepton reconstruction and identification efficiencies, energy scale, and resolution need to be adjusted in the MC calculations to properly describe the data. The appropriate corrections are applied to the MC calculations in order to improve the modeling of the backgrounds.
The processes W=Z þ , W=Z þ jets, and pure QCD jet production give rise to background in addition to prompt leptons, which come from W and Z decay. Jets misidenti-fied as leptons, electrons from photon conversions, and leptons from hadron decays (including b- and c-hadron decays) are classified as instrumental background. The instrumental background accounts for 20% of the
expected e data yield. The dominant component of the instrumental background comes from events with one prompt lepton and one jet identified as a lepton, with an additional contribution from events with two misidentified jets. These sources are referred to as jet instrumental background and are estimated by using data. The back-ground component initiated by prompt photons, referred to as the photon instrumental background, is estimated from MC calculations.
The jet instrumental background is estimated by using data in the following way. Two selections are defined, both requiring at least one lepton satisfying all lepton criteria. The selections are defined by the second lepton candidate: The ‘‘tight’’ selection requires the second candidate to pass all lepton criteria, while the ‘‘loose’’ selection does not enforce the lepton isolation requirement. The probability for a lepton to satisfy the lepton isolation requirement is estimated by applying the loose and tight selections on Z= ! ‘‘ events. The probability for a jet to satisfy the lepton isolation requirement is estimated by applying the loose and tight selections on a sample of QCD dijet events to which a cut on the missing transverse energy EmissT <
15 GeV is applied to remove W þ jets events. These two probabilities, along with numbers of events selected in the loose and tight samples, are used to estimate the back-ground in the final selected sample. The backback-ground is estimated to be 12þ105 events for candidates with one electron and one jet satisfying the muon selection criteria and19þ287 events for candidates with one muon and one jet satisfying the electron selection criteria. The dominant uncertainty on the jet instrumental background estimation comes from the pT dependence of the probability for a
jet to pass the lepton isolation criterion. The background due to two jets satisfying the lepton requirements is esti-mated to be1:3þ51:3events from same-sign dilepton events in the data with the subtraction of contributions estimated from MC calculations for all physics processes except the QCD multijet. The overall jet instrumental background is found to be29þ3010 events. This background level has been checked in simulated samples, which agree with the data-driven estimates.
The dominant photon instrumental background comes from the Wð! Þ and Zð! Þ processes where the photon is reconstructed as an electron. A photon can be reconstructed as an electron if it lies close to a charged particle track or the photon converts to eþe after inter-acting with the material in front of the calorimeter. The photon instrumental background is found to be 4:0 0:7 events.
TableIshows the number of events selected in the data and the estimated background contributions with their uncertainties. A total of 160 e candidates are observed in the data, while the expectation from SM processes is 163þ34
18events. The dominant sources of systematic
the probability for a jet to satisfy the lepton isolation requirement (70% for an electron and 30% for a muon), theoretical cross sections on the physics background pro-cesses (5%–15%), and the integrated luminosity (11%). Other systematic uncertainties from the lepton trigger, reconstruction and identification efficiencies, energy or momentum scale, and resolution have been included and are small.
Since no excess is observed in the data, limits are set for the production of ~in RPV supersymmetric models and an LFV Z0-like vector boson.
The RPV production of ~by d d annihilation decaying into e is considered. By fixing all RPV couplings but 0311 and 312 to zero, the contributions to the e final state
originate from the ~ only. With these couplings, along with the assumption that~is the lightest supersymmetric particle, the ~ can decay only to d d or e. The signal cross section depends on the~mass (m~),
0
311, and 312.
The third-generation~is considered since stringent limits exist on the electron sneutrino and muon sneutrino [1]. The couplings 0311¼ 0:11 and 312 ¼ 0:07, compatible with
the current indirect limits [1], are chosen as a benchmark point.
An e resonance can be generated in models containing a heavy neutral gauge boson with nondiagonal lepton flavor couplings Z0[24]. Very stringent limits on the com-bination of the mass and the coupling to ee and e of such models have been inferred from searches for rare muon decay [2]. By using the data presented in this Letter, a limit on the production cross section times branching ratio to e can be placed on a Z-like vector boson. To calculate the acceptance and efficiency, the Z0 is assumed to have the same quark and lepton couplings as the SM Z.
MC events with~or Z0decaying into e are generated withHERWIG[20,25] orPYTHIA, respectively. Samples are produced with sneutrino masses ranging from 0.1 to 1 TeV and Z0masses from 0.7 to 1 TeV.
The e invariant mass distribution is presented in Fig.1
for data, background contributions, and two possible new physics signals: a ~with m~ ¼ 650 GeV and a Z0 with
mZ0 ¼ 700 GeV. The cross section is 0.31 pb for m~ ¼
650 GeV [26] and 0.61 pb for mZ0 ¼ 700 GeV [27]. The
corresponding overall acceptance times efficiency is 55% for ~and 50% for Z0.
The mespectrum is examined for the presence of a new
heavy particle. For m~< 500 GeV, the search region for
specific m~is defined to beðm~ 3 ; m~ þ 3 Þ, where
is the expected me resolution (e.g., ’ 15 GeV for
m~ ¼ 400 GeV). For higher m~, the region me>
400 GeV is used. The expected and observed 95% C.L. upper limits on ðpp ! ~Þ BRð~! eÞ are
calcu-lated by using a Bayesian method [28] with a flat prior for the signal cross section as a function of m~. Figure 2(a)
shows the expected and observed limits, as a function of m~, together with the 1 and 2 standard deviation
uncertainty bands. The expected exclusion limits are de-termined by using simulated pseudoexperiments contain-ing only SM processes by evaluatcontain-ing the 95% C.L. upper limits for each pseudoexperiment at each value of m~. The
median of the distribution of limits is shown as the ex-pected limit. The ensemble of limits is also used to find the 1 and 2 envelope of the expected limits as a function of m~. For a sneutrino with a mass of 100 GeV (1 TeV), the
limit on the cross section times branching ratio is 0.951 (0.154) pb. The theoretical cross sections for 0311¼ 0:11, 312 ¼ 0:07 and 0311¼ 0:10, 312 ¼ 0:05 are also shown.
Sneutrinos with masses below 0.75 (0.65) TeV are excluded by using 0311¼ 0:11 and 312¼ 0:07 (0311 ¼ 0:10 and
312 ¼ 0:05). The results improve on the previous CDF
95% C.L. limit of 0.56 TeV assuming 0311¼ 0:10 and
312 ¼ 0:05. The 95% C.L. observed upper limits on
0311 as a function of m~ are shown in Fig.2(b)for three
values of 312, together with the exclusion region obtained
from the D0 experiment [7]. The limits derived here are extended to a higher mass region than was available at D0,

even though the limits are worse than those obtained by the D0 Collaboration in the low mass region due to limited statistics.
A similar method is used to set limits on the LFV Z0-like vector boson, by using only events with me> 400 GeV.
After finding no events in the data, the 95% C.L. upper limits on ðpp ! Z0Þ BRðZ0 ! eÞ are set, as shown in Fig.3. The expected limit is the same as the observed limit because the median background event count expectation is also zero. For a Z0 with a mass of 700 GeV (1 TeV), the limit on the cross section times branching ratio is 0.175 (0.183) pb. This result improves upon previous CDF limits by probing a higher mass range of Z0-like vector particles. In conclusion, a search has been performed for a heavy particle decaying into the e final state by using pp
collision data at pffiffiffis¼ 7 TeV recorded by the ATLAS detector. The data are found to be consistent with the SM prediction. Exclusions are placed on two representative models at 95% C.L. In an RPV supersymmetric model, tau sneutrinos with a mass below 0.75 TeV are excluded, assuming single coupling dominance and coupling values 0311 ¼ 0:11 and 312¼ 0:07. Higher values of the RPV
coupling are also excluded as a function of m~. In an LFV
model, extra Z0-like gauge bosons are excluded with a cross section times branching ratio above 0.183 pb, assum-ing mZ0 ¼ 1 TeV. These results extend to higher mass
RPV sneutrinos and LFV Z’s than previous constraints from the Tevatron.
