This Letter presents measurements of the polarization of the top quark in top-antitop quark pair events, using4:7 fb1 of proton-proton collision data recorded with the ATLAS detector at the Large Hadron Collider atpffiffiffis¼7 TeV. Final states containing one or two isolated leptons (electrons or muons) and jets
are considered. Two measurements of‘P, the product of the leptonic spin-analyzing power and the top
quark polarization, are performed assuming that the polarization is introduced by either aCPconserving or a maximally CP violating production process. The measurements obtained, ‘PCPC¼ 0:035

The short lifetime of the top quark [1–5] implies that it decays before hadronization takes place, allowing its spin state to be studied using the angular distributions of its decay products. In the standard model (SM), parity conservation in the strong production of top-antitop quark pairs (tt) in proton-proton (pp) collisions implies zero longitudinal polarization of the quarks. A negligible polarization (0.003) is generated by the weak interaction [6]. Physics beyond the SM can induce top quark polar-ization. For example, models that predict the top quark forward-backward production asymmetry to be larger than the SM prediction, as seen by the Tevatron experi-ments D0 [7,8] and CDF [9], can generate nonzero polarization of top quarks [10–12]. A first study of polarization in ttevents has been performed by the D0 Collaboration [8], showing good agreement between the SM prediction and data.
In this Letter, measurements are presented of the polarization of the top quark in inclusive tt production in single charged lepton (tt!‘qqb b) and dilepton (tt!‘þ‘b b) events. The double differential distribu-tion in polar angles, , of two of the final-state decay products, with respect to a given quantization axis, is given by [13]

where 1 (2) is the angular distribution of the decay
daughter particle of the top (antitop) quark. Here, C rep-resents thettspin correlation,P1(P2) represents the degree
of polarization of the top (antitop) quark along the chosen quantization axis, andiis the spin-analyzing power of the
final-state object [14,15], which is a measure of the sensi-tivity of the daughter particle to the spin state of the parent. At leading order, charged leptons and down-type quarks from W-boson decays are predicted to have the largest sensitivity to the spin state of the top quark with a spin-analyzing power of ¼1. The helicity basis is used, in which the momentum direction of the top quark in the tt
center-of-mass frame is chosen as the quantization axis. Thecos‘ distributions of the charged leptons are used as
observables to extract a measurement of‘P.
The analysis is based on the full 2011 data set of pp
collision events, collected at a center-of-mass energy of 7 TeV by the ATLAS detector [16], corresponding to an integrated luminosity of 4:660:08 fb1 [17] after data quality requirements.
ATLAS includes an inner tracking detector, covering a pseudorapidity [18] range jj<2:5, surrounded by a superconducting solenoid providing a 2 T magnetic field. A liquid argon (LAr) electromagnetic sampling calorimeter (jj<3:2), an iron-scintillator tile hadronic
calorimeter (jj<1:7), a LAr hadronic calorimeter
(1:4<jj<3:2), and a LAr forward calorimeter (3:1<jj<4:9) provide the energy measurements.
The muon spectrometer consists of tracking chambers covering jj<2:7, and trigger chambers covering
jj<2:4, in a toroidal magnetic field. Events considered
in this analysis are required to have one high-transverse-momentum (pT) electron or muon that passes
require-ments of the three-level trigger system.
Both data-driven techniques and Monte Carlo (MC) simulations are used to estimate the sample composition of the data. For each MC sample, generated events are *Full author list given at the end of the article.
processed through a GEANT4 [19] simulation of the full
ATLAS detector [20], and the same reconstruction and analysis software is used for both the data and the MC events. Signal tt events are simulated by the next-to-leading-order (NLO) generator MC@NLO 3.41 [21] with
the NLO parton distribution function (PDF) set CT10 [22], assuming a top quark mass of 172.5 GeV. Parton showering is modeled withHERWIG6.510 [23], andJIMMY
4.31 [24] is used for the underlying event. Attproduction cross section of167þ1718 pbis used, calculated at approxi-mate next-to-next-to-leading order (NNLO) in QCD using
HATHOR 1.2 [25]. Backgrounds are simulated using the MC@NLO, ACERMC [26], ALPGEN [27], and HERWIG
generators, as detailed in Ref. [28]. Each simulated signal or background event is overlaid with additional pp
collisions. The events are given a weight such that the distribution of the average number of events per beam crossing agrees with data. For each sample the cross section is rescaled to the most up-to-date theoretical expectations, as described in Ref. [29].
The data sample is enriched in tt events by applying several selection criteria based on the ttevent topology. The selectedttevents consist of jets, isolated leptons, and missing transverse momentum from the undetected neutri-nos. Jets are reconstructed from clustered energy deposits in the calorimeters using the anti-ktalgorithm [30] with a
radius parameterR¼0:4. Their energies are corrected to
correspond on average to the total energy of the stable particles emitted towards the jet using energy- and
-dependent correction factors derived from simulation, and a residual correction derived from in situ measure-ments [31,32]. They are required to havepT>25 GeVand
jj<2:5. Furthermore, at least 75% of the scalar sum of thepTof all the tracks associated with each jet must belong
to tracks originating from the primary vertex, which is defined as the vertex with the highest sum of the squared
pTvalues of the associated tracks in the event. Jets
origi-nating frombquarks are selected using a neural network algorithm that combines information about the impact parameter significance of tracks with information about explicitly reconstructed secondary vertices and other var-iables. At the chosen working point, the algorithm identi-fies (‘‘btags’’) simulatedbjets from top quark decays with 70% efficiency and a rejection factor of about 140 for light partons [33–35]. Reconstructed electrons must havepT>
25 GeVand be associated with a calorimeter cluster in the rangejclj<2:47, excluding the transition between
calo-rimeter sections,1:37<jclj<1:52. Selected muons are
required to fulfilljj<2:5andpT>20 GeV. Each lepton
is required to pass quality criteria, to be compatible with being produced at the primary vertex by having a longitu-dinal impact parameter smaller than 2 mm, and to be isolated from other calorimeter energy deposits and tracks [36]. TheEmissT is calculated [37] as the magnitude of the negative of the vectorial sum of all energy deposits in the
calorimeters, and then corrected for the momenta of the reconstructed muons.
The details of the final event selection depend on theW
decay channels. This measurement uses five different channels, containing either one or two electrons or muons in the final state, including the ones coming from
decays. The requirements for the single-lepton channels (‘þjets) include (i) exactly one electron or muon; (ii) at least four jets, at least one of which is b tagged; (iii)EmissT >30 GeVfor the electron channel andEmissT >
20 GeV for the muon channel; and (iv) the transverse mass of the W boson to be greater than 30 GeV for the electron channel, while mTþEmissT >60 GeVis required
for the muon channel. The transverse mass is computed from the leptonpTandangle (p‘T,‘) and the direction
of theEmissT asmT¼

. The selection of the dilepton channels (ee, e, ) requires (i) exactly two oppositely charged electrons or muons; (ii) at least two jets; (iii) a dilepton invariant mass larger than 15 GeV for all the channels, and more than 10 GeV away from the Zboson mass for theee and
channels; (iv)EmissT >60 GeVfor theeeandchannels;
and (v) the scalar sum of thepTof all selected leptons and
jets to be larger than 130 GeV for theechannel. The major backgrounds are due to vector boson produc-tion with addiproduc-tional jets, single top quark producproduc-tion, and to misidentified leptons. Their contributions are estimated using data-driven methods and MC simulation. In particu-lar, the normalization of the dominant background in the
‘þjets channels,Wþjets production, is estimated using a measurement of the lepton charge asymmetry in data [38], while the shape of the distribution ofcos‘ is taken
from simulation. In theee() channel, the normalization of theZ= þjets background withZ= decaying intoee
() is determined from data. A Z= þjets enriched control region is defined, where a correction factor for the simulation normalization is derived as a function of the EmissT in the event, and applied to the signal region in
order to account for possibleEmissT mismodeling.
The contributions of nonprompt leptons from semilep-tonic hadron decays and of jets misidentified as leptons (fakes) are determined from data using matrix methods [29,39]. For ‘þjets channels this contribution comes primarily from multijet events, while for dilepton channels it originates primarily from Wþjets events where one charged lepton comes fromW decay and the other lepton is a nonprompt or fake lepton.
After selection, the expected yields for signal and back-ground compared to data are shown in TableI.
In the ‘þjets channels, a kinematic likelihood fit is performed. The likelihood for the event to correspond to a
ttdecay topology is calculated for each possible assign-ment of four jets selected from the up to five jets of highest
pT in the event, to the twob quark jets and the two jets
from theW boson decay [40]. The energies of the jets and the charged lepton, as well as theEmissT , are allowed to vary
within their respective resolutions to best meet the W
boson and top quark mass constraints to form the kinematic likelihood. For each assignment, the combined probability is calculated as the product of the maximum kinematic likelihood, the b tagging efficiencies and light-parton rejection probabilities. The highest probability assignment is chosen as the best reconstruction and used to calculate the charged leptoncos‘.
In the dilepton channels, the neutrino weighting method is used [41]. Because of the presence of two neutrinos from
W boson decays, the final system is underconstrained and assumptions must be made to calculate all particle momenta. Making a hypothesis for the pseudorapidities of the two neutrinos (1,2), a weight is assigned for each
permutation of jets, based on the compatibility of the total neutrino transverse momentum vector and the measured
EmissT , accounting forEmissT resolution [37]. For each event,
10 000 different hypotheses for ð1; 2Þ are scanned,
drawn from the observed probability distribution in the signal MC sample. The configuration with the maximal weight is selected and used to reconstruct the values of cos‘for both charged leptons. Events for which no
physi-cal solution can be found with this method are discarded, corresponding to 15% of the selected events in the simu-lated dilepton ttsample. The assumed distributions of the neutrinos are insensitive to top quark polarization.
To extract the value of ‘Pfrom the data, a fit using
templates for partially polarized top quarks is performed. The signal templates are obtained by reweighting the top and antitop quark decay products in the simulatedtt sam-ple according to Eq. (1) using the helicity basis and setting
Cto the SM value ofttspin correlation,C¼0:31[6]. Two different assumptions about the top quark polarization are made to produce two template fits. In one case, the polar-ization is assumed to be induced by a charge-parity (CP)
conserving process, labeled CPC, which leads to top and antitop quarks having equal values of ‘P and therefore
the same angular distribution for the daughter particles. In the other, maximalCPviolation, labeled CPV, is assumed, leading to opposite values of ‘Pfor the top and antitop
quarks. In this case, when a value of‘Pis quoted its sign
refers to the sign of the coefficient for positively charged leptons. The positive and negative templates used in the fit are built assuming a value of ‘P¼ 0:3, to guarantee
that the differential decay distribution is positive for all values of cos‘ given the degree of spin correlation. The
fraction,f, of the positive template component and thett
production cross section are fitted simultaneously, in order to reduce the influence of normalization uncertainties on the measured polarization. The polarization is computed as
‘P¼0:6f0:3.
For all the considered channels, a template fit is per-formed with a binned maximum likelihood method on the positive lepton and on the negative lepton distributions. Channels are combined by multiplying their respective likelihood functions. The fitting method is unbiased, which was shown using pseudoexperiments.
For each source of systematic uncertainty, new tem-plates corresponding to the respective 1 standard deviation up and down variation are considered. When an uncertainty is evaluated as the difference between two points, it is symmetrized around the central value. The mean of the distribution of the respective differences between the cen-tral fit values and the up and down results from 1000 pseudodata sets is taken as the systematic uncertainty on that source. Systematic uncertainties arising from the same source are treated as being correlated between the different lepton charge and flavor samples.
Detector systematic uncertainties, related to the deter-mination of the energy or momentum scales, resolutions, and efficiencies for jets, electrons, and muons, as well as theEmissT , are considered [32,37,42–46]. Simulated samples
are corrected in order to match the reconstructed object properties observed in data, and the correction factors are varied depending on the uncertainties of their values, in order to estimate the uncertainty on the final measurement. The largest uncertainty in this measurement comes from the jet energy scale.
[image:4.612.51.298.107.190.2]Systematic uncertainties from the modeling of tt pro-duction are accounted for using alternative signal tem-plates. These templates are produced by varying the MC event generator, initial- and final- state radiation, color reconnection, fragmentation modeling, and the PDF sets, as detailed in Ref. [47]. The estimation of the uncertainty due to the top quark mass is performed by repeating the fitting procedure using seven samples with different mass settings in the simulation, and interpolating the change in the parameter f corresponding to a variation of the top quark mass of 1:4 GeV[48] around the nominal value. Because an assumption on the degree of spin correlation is TABLE I. Expected signal and background rounded yields

made when constructing the template, an additional uncer-tainty is applied based on the difference in the parton-level spin correlation in simulated tt events between the
MC@NLOandPOWHEG[49] generators.
For theWþjets background in the‘þjets final state, the overall normalization is varied according to the residual uncertainty after the rescaling based on the measured charge asymmetry [38]. In addition, theWþjets template is varied in shape and normalization by reweighting events according to both the uncertainty in the associated heavy quark production flavor fractions and the parameters of the simulation of extra jets [39]. For the estimate of the sys-tematic uncertainty due to events with nonprompt or fake leptons, the templates are varied according to the uncer-tainties in the matrix method inputs [29,39]. The MC statistical uncertainty is taken into account by performing pseudoexperiments, where the bin content of each template is varied independently according to the uncertainty. TableIIsummarizes the sources of systematic uncertainty and their effect on ‘P for the combined fit. The two
largest uncertainties come from jet reconstruction and MC modeling, both affecting the shape of the cos‘
distribution. For sources of systematic uncertainty that do not depend on the lepton charge in the event, the uncer-tainty in the CP violating scenario is greatly reduced. These uncertainties push the fit parameters in opposite directions for the samples with different lepton charge, leading to a smaller total uncertainty in the combination.
The results of the fit to the data in the single-lepton and dilepton channels are summarized in Table III. Figure 1
shows the fitted observable in the single-lepton and dilep-ton final states with the CP conserving hypothesis, and Fig. 2 shows the same observable in the CP violating hypothesis. The deviation from the expected linear behav-ior of the cos‘ distributions is primarily a result of the
detector acceptance. The combined results are

in theCPconserving scenario, and
‘PCPV¼0:0200:016ðstatÞþ00::013017ðsystÞ (3)
in the CP violating scenario. The polarization in both scenarios agrees with the SM prediction of negligible polarization. The fitted ttis in good agreement with the
SM prediction as obtained from NNLO QCD calculations [50,51].
