(Received 14 February 2012; published 26 June 2012)
A search is presented for production of a heavy up-type quark (t0) together with its antiparticle, assuming subsequent decay to a W boson and a b quark, t0t0! WþbWb. The search is based on 1:04 fb1of proton-proton collisions atpffiffiffis¼ 7 TeV collected by the ATLAS detector at the CERN Large
Hadron Collider. Data are analyzed in the leptonþ jets final state, characterized by a high transverse momentum isolated electron or muon, high missing transverse momentum, and at least three jets. No significant excess of events above the background expectation is observed. A 95% C.L. lower limit of 404 GeV is set for the mass of the t0 quark.

The discovery of the top quark [1] completed the third generation of fundamental fermions in the quark sector of the standard model (SM) of particle physics. It is natural to ask whether heavier quarks may exist. These quarks are often present in new physics models aimed at solving the limitations of the SM. For example, models with a fourth generation of heavy chiral fermions could provide new sources of CP violation to explain the matter-antimatter asymmetry in the Universe and allow for a heavier Higgs boson while remaining consistent with precision electro-weak data [2]. The latter is accomplished by keeping a small mass splitting between the heavy up-type quark (t0) and the heavy down-type quark (b0). Assuming that mt0
mb0< mW, where mW is the W boson mass, results in the t0
quark predominantly decaying to a W boson and a down-type quark q (q ¼ d; s; b). Another possibility is the addi-tion of isospin singlets or doublets of vectorlike quarks, which appear in many extensions of the SM such as little Higgs or extra-dimensional models [3]. In both scenarios, the t0quark can decay into Wb with a large branching ratio, provided there is a significant mixing with the third gen-eration of quarks, consistent with the existing mass and mixing patterns of the known quarks.
The high center-of-mass energy and integrated luminos-ity in pp collisions available at the Large Hadron Collider (LHC) offer a unique opportunity to probe these scenarios. At the LHC, these new heavy quarks would be predomi-nantly produced in pairs via the strong interaction for masses below 1 TeV, while for larger masses electro-weak production of single heavy quarks could become the primary production mechanism, depending on the strength
of their interactions with the SM quarks and weak gauge bosons [3].
A search is presented in this Letter for t0t0 production using pp collision data atpffiffiffis¼ 7 TeV collected with the ATLAS detector. It is assumed that the t0 quark decays exclusively into Wb. The lepton þ jets final-state signature is considered, characterized by a high transverse momen-tum (pT) isolated electron or muon, high missing
trans-verse momentum (EmissT ), and at least three jets. Similar searches in this channel have been published by the CDF and D0 Collaborations [4,5]; the most stringent limits preclude the existence of a t0 quark with a mass below 358 GeV at 95% confidence level (C.L.). A search for t0t0in the dilepton final state has been performed by the ATLAS Collaboration [6], excluding a t0 quark with a mass below 350 GeV at 95% C.L. The leptonþ jets signature has also been recently exploited by the ATLAS Collaboration to search for b0b0 ! WtWþt [7].
The ATLAS detector [8] consists of an inner tracking system surrounded by a superconducting solenoid, electro-magnetic and hadronic calorimeters, and a muon spec-trometer. The inner detector is immersed in a 2 T axial magnetic field and consists of pixel and silicon microstrip detectors inside a transition radiation tracker, providing charged particle tracking in the region jj < 2:5 [9]. The electromagnetic calorimeter is based on lead–liquid-argon (LAr). Hadron calorimetry is based on two different detec-tor technologies, with scintilladetec-tor tiles or LAr as active media and with either steel, copper, or tungsten as the absorber material. The calorimeters provide coverage up to jj < 4:9. The muon spectrometer consists of super-conducting air-core toroids, a system of trigger chambers covering the rangejj < 2:4, and high-precision tracking chambers allowing muon momentum measurements withinjj < 2:7.
The data set used in this analysis was recorded between March and June 2011 by using single electron and muon triggers and includes only events collected under stable

beam conditions and for which all detector subsystems were fully operational. The corresponding integrated lumi-nosity is 1:04 fb1. The event selection criteria closely follow those used in recent ATLAS top quark studies, e.g., Ref. [10]. Electron candidates are required to satisfy pT> 25 GeV and jj < 2:47, excluding the transition
region 1:37 < jj < 1:52 between the barrel and end cap electromagnetic calorimeters. Muon candidates are re-quired to satisfy pT> 20 GeV and jj < 2:5. The pT
threshold requirement ensures that the selected leptons are in the efficiency plateau of the single-lepton triggers. Background from multijet production is suppressed by a requirement of EmissT > 35ð20Þ GeV [11] in the electron
(muon) channel, followed by EmissT þ mT > 60 GeV,
where mT is the transverse mass of the lepton and EmissT
[12]. The EmissT is constructed from the vector sum of all
calorimeter cells contained in topological clusters [13], calibrated at the energy scale of the associated high-pT
object, and including contributions from selected muons. Further requirements are that there be at least three jets with pT> 25 GeV and jj < 2:5, with at least one jet
satisfying pT > 60 GeV. Jets are reconstructed with the
anti-ktalgorithm [14] with radius parameter R ¼ 0:4, from
topological clusters of energy deposits in the calorimeters calibrated at the electromagnetic scale. These jets are then calibrated to the particle level [15] by using a pT- and
-dependent correction factor derived from simulated events and validated by using data. Finally, to further reduce the backgrounds, at least one jet is required to be identified as originating from the hadronization of a b quark (b tagging). This is achieved via an algorithm [16] using multivariate techniques to combine information from the impact parameters of displaced tracks as well as topo-logical properties of secondary and tertiary decay vertices reconstructed within the jet; a working point is used with 70% efficiency for b-quark jets and a rejection factor of 100 for jets originating from light quarks (u, d, s) or gluons. Events with exactly one electron or one muon and with exactly three jets or with four or more jets are ana-lyzed separately to take advantage of their different
signal-to-background ratio and background composition, as discussed below.
After event selection, the main background is tt produc-tion, followed by the production of a W boson in association with jets (W þ jets). Smaller contributions arise from mul-tijet events, single top quark, Z þ jets, and diboson produc-tion. All of the backgrounds which do not involve top quarks are significantly suppressed by the b-tagging re-quirement. Multijet events contribute to the selected sample via the misidentification of a jet or a photon as an electron or the presence of a nonprompt lepton, e.g., from a semilep-tonic b- or c-hadron decay. The normalization and shape of the multijet background kinematic distributions are esti-mated via data-driven methods [11]. For the W þ jets back-ground, the shape is estimated from the simulation, but the normalization is estimated from the asymmetry between Wþþ jets and Wþ jets production [17] in the data. All other backgrounds, as well as the signal, are estimated from the simulation and normalized to their theoretical cross sections. A summary of the background estimates in each of the four channels analyzed and a comparison with the observed yields in data are presented in TableI, showing a good agreement within the uncertainties.
Monte Carlo (MC) samples of tt and single top quark background are generated by using MC@NLO v3.41 [18], assuming a top quark mass of 172.5 GeV, using theCTEQ6.6
set of parton distribution functions (PDFs) [19], and are normalized to the approximate next-to-next-to-leading-order (NNLO) theoretical cross sections [20,21]. Samples of W=Z þ jets background are generated by usingALPGEN V2.13 [22] and the CTEQ6L1 PDF set [19]. The Z þ jets background is normalized to the NNLO theoretical cross section [23], while the W þ jets background normalization is extracted from the data. BothMC@NLOandALPGENare
interfaced toHERWIGv6.5 [24] to model the parton shower
and fragmentation, while JIMMY [25] is used to simulate
the underlying event. The diboson backgrounds are mod-eled by using HERWIGv6.5 and normalized to their NLO
theoretical cross sections [26]. The signal is modeled by usingPYTHIA6.421 [27]. Signal samples are generated for TABLE I. Number of events observed compared to the background expectation after final
event selection in each of the four channels considered. Also shown are the expected signal yields assuming mt0 ¼ 400 GeV. The quoted uncertainties are prior to the fit to data and include

a range of masses mt0 from 250 to 500 GeV in steps of
50 GeV and are normalized to the approximate NNLO theoretical cross sections [20] using the CTEQ6.6 PDF. The MC samples generated by using HERWIG or PYTHIA
use the MRST2007 LO* PDF set [28]. All MC samples
include multiple pp interactions and are processed through a full simulation [29] of the detector geometry and re-sponse using GEANT4 [30] and the same reconstruction software as the data. Simulated events are corrected to match the object identification efficiencies and resolutions determined in data control samples. The total signal detection efficiency, considering both lepton flavors and jet multiplicities analyzed, ranges from 5.2% for mt0 ¼
250 GeV to 17.3% for mt0 ¼ 500 GeV.
This analysis uses the reconstructed heavy quark mass (mreco) as the primary discriminating variable. In the case
of events with 4 jets, mrecois estimated by performing a
kinematic likelihood fit [17] to the t0t0! WþbWb ! ‘bq q0b hypothesis, imposing the constraints that t0 and t0 have the same mass and that the mass of the
lepton-neutrino system, as well as that of a jet pair, equals the nominal W boson mass. The final-state objects considered are the lepton, EmissT , and the four jets with highest pT.
Among all possible jet-parton permutations, the one yield-ing the highest likelihood value after maximization over the fit parameters is kept. In the case of events with exactly three jets, mreco is taken to be the invariant mass of the
three-jet system. In order to ensure a robust background prediction in the tail of the mreco distribution, a dynamic
binning scheme is adopted; starting from the high side and low side of the distributions, bins are merged until the statistical uncertainty in the sum of the background pre-dictions in that bin drops below 5%.
Systematic uncertainties affecting the normalization and shape of the mrecodistribution are estimated for both signal
and background, taking into account correlations among processes as well as channels. The dominant sources of uncertainty arise from the modeling of the tt background. The uncertainties on the tt background come from the theoretical uncertainty on the cross section (þ7:09:6%) as well as the effects on both normalization and shape of the mrecodistribution from a number of sources; these are
uncertainties on the fragmentation model (based on the comparison ofHERWIGandPYTHIAfragmentations), on the NLO event generator (based on the comparison of
MC@NLO and POWHEG [31]), and on the top quark mass
(taken to be1 GeV).
The uncertainty on the jet energy scale affects the nor-malization of signal (2%–12%) and backgrounds (5%– 30%) modeled through the simulation, as well as the shape of their mrecodistributions.
Uncertainties on the modeling of initial- and final-state QCD radiation, evaluated by varying corresponding generator parameters, are considered as correlated between the tt background and the t0t0 signal.
While the normalization is obtained from the asymmetry measurement, the uncertainties on the normalization of the W þ jets background are derived from measurements of W þ 2 jets dominated data samples and take into account the uncertainty on the heavy-flavor content of the samples as well as the extrapolation to higher jet multiplicities. The total uncertainty on the W þ jets normalization is 50% and 70% for events with exactly 3 jets and 4 jets, respec-tively. Uncertainties on the shape of the mreco distribution
for the W þ jets background are estimated by varying the choices of the matching scale (from 15 to 10 GeV) and the factorization scale (from 2F ¼ m2W þ
P
p2T;jet to 2F ¼
m2Wþ p2T;W) inALPGEN.
Uncertainties on the modeling of the b-tagging algo-rithms affect the identification of b=c jets (6%–8% for signal and backgrounds containing top quarks and 6%–12% for the other backgrounds) as well as the mis-identification of light jets (< 0:5% for signal and back-grounds containing top quarks and up to 5% for the other backgrounds). The Z þ jets, single top, and diboson back-grounds are varied within the uncertainty on their theoreti-cal cross sections. The uncertainty on the multijet background event normalizations is conservatively taken as 100%. Uncertainties on the shapes of the multijet back-ground are derived by varying the lepton identification criteria used to extract this background.
The uncertainties on the lepton identification and trigger efficiencies, as well as their energy scales and resolutions, impact the yields by 3% for electrons and 6% for muons.
Uncertainties on the integrated luminosity (3.7%) [32], jet reconstruction efficiency, jet resolution modeling, effect of multiple pp interactions on the modeling of the EmissT ,
and treatment of imperfections in the detector description in the MC simulation are also considered and are all found to have a very small effect on the result.
Good agreement between the data and the background prediction is observed in terms of both overall normaliza-tion and shape of the mrecodistribution. The mreco
distribu-tion is analyzed by using a log-likelihood ratio LLR ¼ 2 logðLsþb=LbÞ as a test statistic, where Lsþb
(Lb) is a Poisson likelihood to observe the data under the
signal-plus-background (background-only) hypothesis. The per-bin signal and background predictions are parame-terized in terms of 12 nuisance parameters, describing the effect of leading sources of systematic uncertainty such as jet energy scale, initial- and final-state QCD radiation, and tt, W þ jets, and QCD multijet normalizations. The impact of systematic uncertainties on the sensitivity of the search is reduced by maximizing both likelihood functions, Lsþb and Lb, with respect to these nuisance parameters,
subject to Gaussian constraints of their prior values. The set of fitted nuisance parameters is chosen based on their over-all impact on the search sensitivity, the expected constrain-ing power of the data, and their suitability to be treated as continuous parameters. The simultaneous constraint of
several of these systematic uncertainties is possible because of the inclusion of the 3-jet channel in the analysis. The latter has a higher fraction of W þ jets background than the 4-jets channel and provides sensitivity to event migration to different jet multiplicities when varying uncertainties such as jet energy scale or initial- and final-state QCD radiation. In addition to the jet multiplicity spectrum, the jet energy scale affects the peak position of the mreco
spec-trum for tt background and can be constrained owing to the small uncertainty on the measured top quark mass [33]. Nuisance parameters associated with smaller systematic
uncertainties (e.g., lepton identification or trigger) are only weakly constrained.
Figure1shows a comparison of the postfit mreco
distri-bution between the data and the background prediction for the combined e= þ 3 jets and e=þ 4 jets channels. The fitted parameters are typically within 1 standard de-viation of their nominal values, and their uncertainties are consistent with expectations based on pseudoexperiments. Several additional studies were performed to check the integrity of the fitting procedure. The likelihood was veri-fied to be parabolic near the minimum for each of the fitted parameters and to yield reasonable fit uncertainties; the lack of sensitivity to the assumed pT and correlation of
the jet energy scale uncertainty was verified.
In the absence of any significant data excess, either in the e þ jets or þ jets channels individually or in their combination, 95% C.L. upper limits on the t0t0production cross section are derived by using the CLS method [34],
which employs the LLR test statistic described above. Pseudoexperiments are generated under both the signal-plus-background (s þ b) and background-only (b) hypoth-eses, taking into account per-bin statistical fluctuations of the total predictions according to Poisson statistics, as well as Gaussian fluctuations in the signal and background expectations describing the effect of systematic uncertain-ties. The fraction of s þ b and b pseudoexperiments with LLR larger than the median or observed LLR defines CLsþb and CLb for the expected or observed limits,
re-spectively. Signal cross sections for which CLs¼
CLsþb=CLb< 0:05 are deemed excluded at the 95% C.L.
The resulting observed and expected upper limits on the t0t0 production cross section are shown in Fig. 2 as a function of the t0 mass, compared to the theoretical prediction, assuming a BRðt0! WbÞ ¼ 1. As a result, an

In summary, a search for t0t0 production has been per-formed in the leptonþ jets final state under the assumption BRðt0! WbÞ ¼ 1. No significant excess of events in the tail of the mreco distribution was found, resulting in an
observed lower limit of mt0> 404 GeV at 95% C.L. This
represents the most stringent limit to date. This limit is also directly applicable to a down-type vectorlike quark with electric charge of4=3 decaying into a W boson and a b quark [3].
