This Letter presents a search for tb (t¯b or ¯tb) resonances using data collected in 2011 by the ATLAS detector [1] at the Large Hadron Collider (LHC), corresponding to an integrated luminosity of 1.04 ± 0.04 fb−1 _{[2, 3] from}

pp collisions at a center-of-mass energy of 7 TeV. These resonances include new heavy gauge bosons such as the W′ _{boson. The W}′ _{boson is a charged heavy gauge}

bo-son that is predicted in many extensions of the Standard Model (SM) such as universal extra dimensions [4] and little Higgs models [5]. If the W′ _{boson is assumed to}

have similar coupling strengths to those of the SM W boson, searches in the W′ _{→ ℓν decay channel, where}

ℓ is a charged lepton, are the most sensitive. However, the W′ _{→ tb channel is competitive if W}′ _{→ ℓν decay}

is suppressed. For example, for a right-handed W′ R this

can happen if the right-handed neutrino, νR, is heavy

enough to prevent W′

R → ℓνR decay [6]. The model of

a right-handed W′

R with SM-like couplings is chosen as

the benchmark model for the analysis presented in this Letter. The W′

R → tb decay channel has been searched

for at the Tevatron [7, 8]. The best previous limit on a W′

R with Standard Model-like couplings of the W′ to

quarks was set by the D0 experiment and excludes a W′ R

mass below 890 GeV at 95% confidence level.

The innermost part of the ATLAS detector [9], a track-ing system in a 2 T axial magnetic field, measures the momentum of the charged particles produced in the colli-sions. Outside of the solenoid are the calorimeter subsys-tems, which measure the electron, photon, and hadronic particle energies, and the muon spectrometer which is used to identify and measure the momentum of muons in a toroidal magnetic field. A three-level trigger sys-tem [10] reduces the event rate and selects the events for analysis.

The tb resonances are searched for in the tb → ℓνbb decay channel, where the lepton, ℓ, is either an electron or a muon. W′

R signal events are simulated to leading

order (LO) with the PYTHIA v6.421 [11] Monte Carlo

(MC) generator, using the MRST2007 LO* parton distri-bution functions (PDFs) [12]. Seven signal samples are simulated, with different W′

R mass assumptions, ranging

from 500 GeV to 2.0 TeV, as reported in Table I. The respective signal cross section times the branching ratio values are computed at next-to-leading-order (NLO) [13], using CTEQ6.6 PDFs [14]. mW′ R [GeV] B(W ′ R→tb) σ × B [pb] 500 0.298 ± 0.002 54.6 ± 2.1 750 0.319 ± 0.001 10.9 ± 0.6 1000 0.326 ± 0.001 2.92 ± 0.18 1250 0.328 ± < 0.001 0.91 ± 0.07 1500 0.330 ± < 0.001 0.31 ± 0.03 1750 0.331 ± < 0.001 0.11 ± 0.01 2000 0.332 ± < 0.001 0.044 ± 0.005

production cross section times the branching ratio value,

center-of-mass energy [13]. The uncertainties on the branching ratios are due to the top quark mass uncertainty. The uncertainties

on the cross sections include statistical, αs, NLO

renormal-ization and factorrenormal-ization scales, and PDF uncertainties.

Data-driven methods and MC simulated samples are used to estimate and model backgrounds. The t¯t pro-cess is simulated with the MC@NLO v3.41 [15, 16] MC generator, assuming a top quark mass of 172.5 GeV, and using the CTEQ6.6 PDFs. The parton shower is added using the HERWIG [17] and JIMMY [18] MC genera-tors. The t¯t cross section is obtained from the approx-imate NNLO prediction calculated with the HATHOR program [19] using the MSTW2008 NNLO PDF sets [20]. The single top quark processes are simulated using the AcerMC _{v3.7 [21] MC generator and hadronization is} performed with the PYTHIA MC generator; the cross section is calculated to approximate NNLO [22–24] using the CTEQ6.6 PDFs. Diboson processes are simulated

using the HERWIG v6.5 MC generator and their cross sections are obtained at NLO using the MCFM [25] pro-gram with the MSTW2008 PDFs. The MC samples sim-ulated with the AcerMC and HERWIG MC generators use the MRST2007 LO* PDFs. Vector boson produc-tion in associaproduc-tion with jets (W + light jets, W b¯b, W c¯c, W c and Z+jets with up to five additional partons) is simulated using the ALPGEN v2.13 [26] MC generator, coupled with the CTEQ6L1 PDFs [14] and hadroniza-tion is performed with the HERWIG and JIMMY MC generators. In these samples, additional jets can be cre-ated from the parton shower. In order to avoid double counting between the inclusive W +n parton samples and the parton shower, overlaps are removed following the MLM matching prescription [26]. A cross section correc-tion factor is applied to the LO W /Z+jet cross seccorrec-tions computed by comparing the LO and NLO predictions from the FEWZ [27] program. The W c cross section correction factor is obtained using the MCFM [28] pro-gram with the CTEQ6.6 PDFs. All samples are passed through the full simulation of the ATLAS detector [29] based on GEANT4 [30] and are then reconstructed us-ing the same procedure as collision data. The simulated samples include the effect of multiple pp collisions per bunch crossing (pile-up) which on average is six events per bunch crossing. In order to ensure a good description of the energy scale and resolution, the trigger, the recon-struction and identification efficiency, corrections based on comparisons between data and MC events are applied to the simulated signal and background samples. The corresponding scale factors are obtained as a function of the object kinematics, resulting in final corrections of the order of a few percent.

Candidate events are identified using single high trans-verse momentum electron and muon triggers and strin-gent detector and data quality requirements. For each candidate, two jets, one isolated charged lepton, and missing transverse momentum, Emiss

T , are required. The

definition of the objects and details of a similar event se-lection including lepton isolation requirements are given in Ref. [31]. The reconstructed charged lepton is required to have a transverse momentum pT>25 GeV to ensure

a constant trigger efficiency, |η| < 2.5 for a muon [32– 34] and |η| < 2.47 for an electron [35] (the calorimeter transition region 1.37 < |η| < 1.52 is excluded), and to lie within ∆R = p(∆η)2_{+ (∆φ)}2 _{<0.15 of the}

corre-sponding triggered lepton. Jets are reconstructed from energy clusters in the calorimeters with the anti-kt

al-gorithm [36] with a radius parameter R = 0.4 and cal-ibrated to the hadronic energy scale [37]. Exactly two jets with pT>25 GeV and |η| < 2.5 are required in the

event, and at least one of them must be tagged as a b-jet. The b-tagging algorithm uses measurements of the impact parameters of tracks and the properties of recon-structed vertices; these are combined in a neural network to extract a tagging decision for each jet [38]. Based on a

t¯tMC sample, the working point is chosen at a b-tagging efficiency of 57%, leading to a light-quark tagging proba-bility of 0.2% derived from the same sample. To account for the differences between observed and simulated jet pT and η distributions, the b-tagging efficiency and the

corresponding scaling factors to be applied to MC are derived from data [39]. Events before applying any b-tagging are referred to as pre-tagged events. Events where one or both jets are b-tagged are referred to as single- or double-taggedevents respectively.

The Emiss

T is calculated using calorimeter energy

clus-ters [40] calibrated according to the reconstructed physics object to which they are associated [41]; events are re-quired to satisfy Emiss

T >25 GeV. The background

contri-bution from multiple hadron jets (multijet background) is reduced by imposing a requirement on the sum of the W boson transverse mass mT(W ) [42] and ETmiss:

mT(W ) + ETmiss> 60 GeV [43]. After applying all

se-lection criteria, the acceptance times efficiency for W′ R

signal events with mW′

R = 1.0 TeV is 1.38% for

single-tagged events and 0.49% for double-single-tagged events. One of the most important backgrounds for the tb res-onance search comes from W production in association with either heavy-flavor jets, or light-flavor jets misiden-tified as b-jets. Multijet production is another source of background, when either a hadronic jet is misidentified as a lepton, or when a real high-pTlepton from

semilep-tonic decay of a heavy hadron within a jet fulfills the selection requirements. Another important background comes from t¯t pair production in the case that one W boson decays leptonically and the decay products of the other W boson are lost due to the detector acceptance. Other smaller backgrounds come from single top produc-tion, diboson production and Z+jet events.

Kinematic variable distributions for the W +jet back-ground are taken from MC samples, while the overall nor-malization and flavor composition are derived from data; this is done after rejecting signal-like events with the tb invariant mass, mtb which is described later, satisfying

mtb >500 GeV. In each jet multiplicity bin, the

num-ber of W +jet events in the data is assumed to be the difference between the number of observed data events and the number of events estimated for SM non-W +jet processes including the multijet process estimated from a data-driven method. The overall W +jet normalization factor is the ratio of the number of W +jet events in the data to the number of W +jet events in simulation. The flavor composition of the W +jet background is estimated by comparing the MC prediction to data while its depen-dence on jet and b-tagging multiplicity is modeled using MC. The fractions of W b¯b, W c¯c, W c and W +light jet components of the total W +jet MC are scaled such that the background sum equals the observed data in three separate samples: a single-tagged one-jet sample and the pre-tagged and single-tagged two-jet samples. The same scale factor is used for W b¯b and W c¯c.

The multijet background normalization and the shape of each distribution are obtained from data. The shape of each multijet background distribution is taken from a data sample which requires a jet instead of an isolated lepton. This jet is required to have a detector signature similar to an electron: it must have pT>25 GeV and

be-tween 80% and 95% of its energy deposited in the electro-magnetic section of the calorimeter. The jet must also be associated with at least four tracks. The normalization is estimated using a binned likelihood fit to the Emiss

T

distri-bution in data in which the normalization of the W +jet and the multijet components is allowed to vary. The fit is performed separately in the pre-tagged, single- and double-tagged samples, after applying all selection crite-ria except the Emiss

T cut. The uncertainty on the multijet

rate is 50% for pre-tagged and single-tagged events, while it amounts to 100% for double-tagged events. The un-certainty is estimated by using the mT(W ) distribution

instead of the Emiss

T distribution in the binned likelihood

fit, and by using multijet background models built from data samples with low and high numbers of pp collisions per event.

The t¯t, single top, Z+jet and diboson events are nor-malized to the theoretical cross sections and the shape of each distribution is taken from the MC simulation.

The tb invariant mass is used as the observable to dis-criminate signal from background. The neutrino momen-tum in the decay tb → ℓνbb is computed assuming the transverse component to be equal to Emiss

T , and

extract-ing the longitudinal component (pz) by constraining the

ℓ-ν invariant mass to mW = 80.42 GeV. This gives a

quadratic equation in pzand the solution with the smaller

|pz| is used. If the solution is complex, only the real part

is taken and the imaginary part is neglected.

tributions of mtb for single- and double-tagged two-jet

events. The data event with the highest mtbvalue

corre-sponds to a single-tagged event with mtb≃ 2.0 TeV. The

Bumphunter_{tool [44] is used to search for a local} ex-cess in the data due to the production of a tb resonance. This tool is used to test the consistency of the data with the SM background only hypothesis, comparing the data to the SM prediction over the spectrum of the tb invari-ant mass, scanning over sliding mass windows from 0.5 to 2.0 TeV. The width of the mass windows is chosen to be constant in log(mtb) as shown in Fig. 1 to deal

with low background MC statistics in the higher mass bins. This comparison has been performed for single-and double-tagged events separately. The region with the highest data-background difference is 1024–1129 (764– 842) GeV for single(double)-tagged events. The probabil-ity of observing the SM background fluctuating up to or above the number of observed data events in these regions is 0.66 for single-tagged events and 0.72 for double-tagged events. These values, which are based on the statistical error only, indicate that there is no significant evidence for tb resonances in the observed data.

Systematic uncertainties from various sources affecting the background and the signal acceptance (rate uncer-tainty), as well as shape changes in the invariant mass distribution (shape uncertainty) are considered.

The jet energy scale and the uncertainty on the b-tagging scale factors are the dominant systematic un-certainties for the signal. The background normalization yields are the dominant systematic uncertainty for the background contribution. The jet energy scale uncer-tainty is evaluated by scaling 1σ up or down the energy of each jet. The b-tagging scale factors are pT-dependent

and have an uncertainty between 8% and 20%. The multijet background uncertainty has already been de-scribed. The uncertainty on the normalization of the W+jets background and its flavor composition include

both systematic contributions and a statistical contribu-tion from the limited size of the sample. The W +jet fla-vor uncertainties are treated as fully correlated between W b¯b and W c¯c and uncorrelated otherwise. Theoretical cross section uncertainties for the top (t¯tand single top), diboson and Z+jet backgrounds of 10%, 5% and 60% are assigned, respectively. The Z+jet theoretical cross section uncertainty is estimated based on the variation of ALPGEN parameters, and a relative uncertainty of 50% on the heavy-quark contributions, but it has a very small impact on the result due to the small contribu-tion of Z+jet events. Systematic uncertainties due to the residual differences between data and MC simulation for the reconstruction and energy calibration of jets,

elec-trons and muons are estimated to have a small impact on the result. The uncertainty on the integrated luminosity is 3.7% [3]. The uncertainty on the background model-ing in the mtbdistribution is evaluated using pre-tagged

data and found to be negligible.

An uncertainty due to the MC event generator is esti-mated by comparing MC@NLO and POWHEG [45, 46] for t¯tand AcerMC and MC@NLO for single top events. The uncertainty in parton shower modeling is estimated by comparing two POWHEG t¯t samples for which the hadronization is performed by PYTHIA or HERWIG. Uncertainties from modeling the amount of initial and final-state QCD radiation are also taken into account. The uncertainty due to the specific choice of PDFs in the simulated events is determined by re-weighting the MC events using the NNPDF20, MSTW2008 and CTEQ6.6 [20] eigenvector PDF sets. Finally, an uncer-tainty to account for the limited MC sample sizes is also included.

No significant data excess is identified for any value of mtb, and an upper limit on the WR′ → tb production cross

section (σ) times the B(W′

R → tb) at 95%

credibility-level (CL) is determined using a Bayesian approach as-suming flat priors [47]. The likelihood function used is the product of the Poisson probabilities over all mass bins [48] per channel. The combination of single- and double-tagged events is done by extending the likelihood function; the joint likelihood is the product of Poisson probabilities for each individual bin in each channel. Sys-tematic and statistical uncertainties are incorporated and treated as nuisance parameters with a Gaussian proba-bility density function. Figure 2 shows the observed and the expected limits from single- and double-tagged events combined. Observed (expected) upper limits obtained on σ(pp → W′

R) × B(WR′ → tb) at 95% CL lie in the range

6.1 – 1.0 (4.5 – 1.4) pb for W′

R masses ranging from 0.5

to 2.0 TeV. These σ × B limits are also applicable to a left-handed W′_{. The σ × B limits are converted into}

mass limits using the intersection between the theoreti-cal σ × B curve as a function of mW′

R and the expected

and observed σ × B limit curves. The corresponding ob-served (expected) 95% CL lower limit is: mW′

R > 1.13

(1.13) TeV. These are currently the most stringent direct limits on production of W′

R→ tb.
