ABSTRACT: A combined search for the Standard Model Higgs boson with the ATLAS
experiment at the LHC using datasets corresponding to integrated
luminosities from 1.04 fb-1 to 4.9
fb-1 of pp collisions collected at s=7 TeV is
presented. The Higgs boson mass ranges 112.9-115.5 GeV,
131-238 GeV and 251-466 GeV are excluded at the 95%
confidence level (CL), while the range 124-519 GeV is expected to
be excluded in the absence of a signal. An excess of events is observed
around mH˜126 GeV with a local significance of 3.5
standard deviations (σ). The local significances of
H→γγ,
H→ZZ→ℓ+ℓ-ℓℓ
and
H→WW→ℓ+νℓν¯,
the three most sensitive channels in this mass range, are 2.8σ,
2.1σ and 1.4σ, respectively. The global probability for the
background to produce such a fluctuation anywhere in the explored Higgs
boson mass range 110-600 GeV is estimated to be ˜1.4% or,
equivalently, 2.2σ.

ABSTRACT: A search for new phenomena in tt events with large missing transverse momentum in proton-proton collisions at a center-of-mass energy of 7 TeV is presented. The measurement is based on 1.04 fb(-1) of data collected with the ATLAS detector at the LHC. Contributions to this final state may arise from a number of standard model extensions. The results are interpreted in terms of a model where new top-quark partners are pair produced and each decay to an on-shell top (or antitop) quark and a long-lived undetected neutral particle. The data are found to be consistent with standard model expectations. A limit at 95% confidence level is set excluding a cross section times branching ratio of 1.1 pb for a top-partner mass of 420 GeV and a neutral particle mass less than 10 GeV. In a model of exotic fourth generation quarks, top-partner masses are excluded up to 420 GeV and neutral particle masses up to 140 GeV.

ABSTRACT: A measurement of the ZZ production cross section in proton-proton collisions at sqrt[s] = 7 TeV using data corresponding to an integrated luminosity of 1.02 fb(-1) recorded by the ATLAS experiment at the LHC is presented. Twelve events containing two Z boson candidates decaying to electrons and/or muons are observed, with an expected background of 0.3 ± 0.3(stat)(-0.3)(+0.4)(syst) events. The cross section measured in a phase-space region with good detector acceptance and for dilepton masses within the range 66 to 116 GeV is σ(ZZ → ℓ+ ℓ- ℓ+ ℓ-)(fid) = 19.4(-5.2)(+6.3)(stat)(-0.7)(+0.9)(syst) ± 0.7(lumi) fb. The resulting total cross section for on-shell ZZ production, σ(ZZ)(tot) = 8.5(-2.3)(+2.7)(stat)(-0.3)(+0.4)(syst) ± 0.3(lumi) pb, is consistent with the standard model expectation of 6.5(-0.2)(+0.3) pb calculated at the next-to-leading order in QCD. Limits on anomalous neutral triple gauge boson couplings are derived.

ABSTRACT: This Letter reports on a search for narrow high-mass resonances decaying into dilepton final states. The data were recorded by the ATLAS experiment in pp collisions at √s=7 TeV at the Large Hadron Collider and correspond to a total integrated luminosity of 1.08 (1.21) fb(-1) in the e(+)e(-) (μ(+)μ(-)) channel. No statistically significant excess above the standard model expectation is observed and upper limits are set at the 95% C.L. on the cross section times branching fraction of Z' resonances and Randall-Sundrum gravitons decaying into dileptons as a function of the resonance mass. A lower mass limit of 1.83 TeV on the sequential standard model Z' boson is set. A Randall-Sundrum graviton with coupling k/M(Pl)=0.1 is excluded at 95% C.L. for masses below 1.63 TeV.

ABSTRACT: A search for a Higgs boson has been performed in the H→WW→ℓνjj channel in 1.04 fb(-1) of pp collision data at √s=7 TeV recorded with the ATLAS detector at the Large Hadron Collider. No significant excess of events is observed over the expected background and limits on the Higgs boson production cross section are derived for a Higgs boson mass in the range 240 GeV<m(H)<600 GeV. The best sensitivity is reached for m(H)=400 GeV, where the 95% confidence level upper bound on the cross section for H→WW production is 3.1 pb, or 2.7 times the standard model prediction.

ABSTRACT: The inclusive and dijet production cross-sections have been measured for
jets containing b-hadrons ( b-jets) in proton-proton collisions at a
centre-of-mass energy of sqrt{s} = 7 TeV, using the ATLAS detector at
the LHC. The measurements use data corresponding to an integrated
luminosity of 34 pb-1. The b-jets are identified using either
a lifetime-based method, where secondary decay vertices of b-hadrons in
jets are reconstructed using information from the tracking detectors, or
a muon-based method where the presence of a muon is used to identify
semileptonic decays of b-hadrons inside jets. The inclusive b-jet
cross-section is measured as a function of transverse momentum in the
range 20< p T<400 GeV and rapidity in the range |
y|<2.1. The boverline{b}-dijet cross-section is measured as a
function of the dijet invariant mass in the range 110< m
jj<760 GeV, the azimuthal angle difference between the two
jets and the angular variable χ in two dijet mass regions. The
results are compared with next-to-leading-order QCD predictions. Good
agreement is observed between the measured cross-sections and the
predictions obtained using POWHEG + Pythia. MC@NLO + Herwig shows good
agreement with the measured boverline{b}-dijet cross-section. However,
it does not reproduce the measured inclusive cross-section well,
particularly for central b-jets with large transverse momenta.

ABSTRACT: A search for a heavy standard model Higgs boson decaying via H→ZZ→→ℓ(+)ℓ(-)νν, where ℓ=e, μ, is presented. It is based on proton-proton collision data at √s=7 TeV, collected by the ATLAS experiment at the LHC in the first half of 2011 and corresponding to an integrated luminosity of 1.04 fb(-1). The data are compared to the expected standard model backgrounds. The data and the background expectations are found to be in agreement and upper limits are placed on the Higgs boson production cross section over the entire mass window considered; in particular, the production of a standard model Higgs boson is excluded in the region 340<m(H)<450 GeV at the 95% confidence level.

ABSTRACT: A measurement of the cross-section for
ϒ(1S)→μμ production in
proton-proton collisions at centre of mass energy of 7 TeV is presented.
The cross-section is measured as a function of the ϒ(1S)
transverse momentum in two bins of rapidity, |y|<1.2 and
1.2<|y|<2.4. The measurement requires that both muons
have transverse momentum pTμ>4 GeV and pseudorapidity
|η|<2.5 in order to reduce theoretical uncertainties
on the acceptance, which depend on the poorly known polarisation. The
results are based on an integrated luminosity of 1.13 pb-1,
collected with the ATLAS detector at the Large Hadron Collider. The
cross-section measurement is compared to theoretical predictions: it
agrees to within a factor of two with a prediction based on the NRQCD
model including colour-singlet and colour-octet matrix elements as
implemented in PYTHIA while it disagrees by up to a factor of ten with
the next-to-leading order prediction based on the colour-singlet model.

ABSTRACT: The inclusive J/ψ production cross-section and fraction of J/ψ
mesons produced in B-hadron decays are measured in proton-proton
collisions at s=7 TeV with the ATLAS detector at the LHC, as a function
of the transverse momentum and rapidity of the J/ψ, using 2.3
pb-1 of integrated luminosity. The cross-section is measured
from a minimum p of 1 GeV to a maximum of 70 GeV and for
rapidities within |y|<2.4 giving the widest reach of any measurement
of J/ψ production to date. The differential production
cross-sections of prompt and non-prompt J/ψ are separately
determined and are compared to Colour Singlet NNLO⋆,
Colour Evaporation Model, and FONLL predictions.

ABSTRACT: This Letter presents a measurement of the W+ W- production cross section in sqrt(s) = 7 TeV pp collisions by the ATLAS experiment, using 34 pb(-1) of integrated luminosity produced by the Large Hadron Collider at CERN. Selecting events with two isolated leptons, each either an electron or a muon, 8 candidate events are observed with an expected background of 1.7 ± 0.6 events. The measured cross section is 41(-16)(+20)(stat) ± 5(syst)±1(lumi) pb, which is consistent with the standard model prediction of 44 ± 3 pb calculated at next-to-leading order in QCD.

ABSTRACT: This Letter presents the first search for a heavy particle decaying into an e ± μ(-/+) final state in sqrt[s] = 7 TeV pp collisions at the LHC. The data were recorded by the ATLAS detector during 2010 and correspond to a total integrated luminosity of 35 pb(-1). 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 λ(311)' = 0.11 and λ312 = 0.07. In a lepton flavor violating model, a Z'-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.

ABSTRACT: A search for new interactions and resonances produced in LHC proton–proton (pp) collisions at a centre-of-mass energy was performed with the ATLAS detector. Using a dataset with an integrated luminosity of 36 pb− 1, dijet mass and angular distributions were measured up to dijet masses of ~3.5 TeV and were found to be in good agreement with Standard Model predictions. This analysis sets limits at 95% CL on various models for new physics: an excited quark is excluded for mass between 0.60 and 2.64 TeV, an axigluon hypothesis is excluded for axigluon masses between 0.60 and 2.10 TeV and quantum black holes are excluded in models with six extra space–time dimensions for quantum gravity scales between 0.75 and 3.67 TeV. Production cross section limits as a function of dijet mass are set using a simplified Gaussian signal model to facilitate comparisons with other hypotheses. Analysis of the dijet angular distribution using a novel technique simultaneously employing the dijet mass excludes quark contact interactions with a compositeness scale Λ below 9.5 TeV.

ABSTRACT: Measurements are presented from proton–proton collisions at centre-of-mass energies of , 2.36 and 7 TeV recorded with the ATLAS detector at the LHC. Events were collected using a single-arm minimum-bias trigger. The charged-particle multiplicity, its dependence on transverse momentum and pseudorapidity and the relationship between the mean transverse momentum and charged-particle multiplicity are measured. Measurements in different regions of phase space are shown, providing diffraction-reduced measurements as well as more inclusive ones. The observed distributions are corrected to well-defined phase-space regions, using model-independent corrections. The results are compared to each other and to various Monte Carlo (MC) models, including a new AMBT1 pythia6 tune. In all the kinematic regions considered, the particle multiplicities are higher than predicted by the MC models. The central charged-particle multiplicity per event and unit of pseudorapidity, for tracks with pT>100 MeV, is measured to be 3.483±0.009 (stat)±0.106 (syst) at and 5.630±0.003 (stat)±0.169 (syst) at .

ABSTRACT: Azimuthal decorrelations between the two central jets with the largest transverse momenta are sensitive to the dynamics of events with multiple jets. We present a measurement of the normalized differential cross section based on the full data set (∫Ldt=36 pb(-1)) acquired by the ATLAS detector during the 2010 sqrt(s)=7 TeV proton-proton run of the LHC. The measured distributions include jets with transverse momenta up to 1.3 TeV, probing perturbative QCD in a high-energy regime.

The data were recorded by the ATLAS experiment during 2010 and correspond to a total integrated luminosity of 35 pb(-1). No excess above the standard model background expectation is observed. Limits are set on the parameters of the minimal supergravity framework, extending previous limits. Within this framework, for A(0)=0 GeV, tanβ=3, and μ>0 and for equal squark and gluino masses, gluino masses below 700 GeV are excluded at 95% confidence level.
