Abstract:

A measurement of the Z/γ* transverse momentum (pTZ) distribution in proton-proton collisions at s=7 TeV is presented using Z/γ*→e+e- and Z/γ*→μ+μ- decays collected with the ATLAS detector in data sets with integrated luminosities of 35 pb-1 and 40 pb-1, respectively. The normalized differential cross sections are measured separately for electron and muon decay channels as well as for their combination up to pTZ of 350 GeV for invariant dilepton masses 66 GeV

Abstract:

A search for the Standard Model Higgs boson in the two photon decay channel is reported, using 1.08 fb-1 of proton-proton collision data at a centre-of-mass energy of 7 TeV recorded by the ATLAS detector. No significant excess is observed in the investigated mass range of 110-150 GeV. Upper limits on the cross-section times branching ratio of between 2.0 and 5.8 times the Standard Model prediction are derived for this mass range. © 2011 CERN.

Abstract:

A search for the Standard Model Higgs boson in the decay channel H→ZZ(*)→ℓ+ℓ-ℓ'+ℓ'-, where ℓ=e, μ, is presented. Proton-proton collision data at s=7TeV recorded with the ATLAS detector and corresponding to an average integrated luminosity of 2.1fb-1 are compared to the Standard Model expectations. Upper limits on the production cross section of a Standard Model Higgs boson with a mass between 110 and 600GeV are derived. The observed (expected) 95% confidence level upper limit on the production cross section for a Higgs boson with a mass of 194 GeV, the region with the best expected sensitivity for this search, is 0.99 (1.01) times the Standard Model prediction. The Standard Model Higgs boson is excluded at 95% confidence level in the mass ranges 191-197, 199-200 and 214-224 GeV. © 2011 CERN.

Search for new phenomena with the monojet and missing transverse momentum signature using the ATLAS detector in s=7TeV proton-proton collisions

Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics 705:4 (2011) 294-312

Abstract:

A search for new phenomena in events featuring a high energy jet and large missing transverse momentum in proton-proton collisions at s=7TeV is presented using a dataset corresponding to an integrated luminosity of 33 pb-1 recorded with the ATLAS detector at the Large Hadron Collider. The number of observed events is consistent with the Standard Model prediction. This result is interpreted in terms of limits on a model of Large Extra Dimensions. © 2011 CERN.

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 pT 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. © 2011 CERN.
