Research summary
Output is centred on the ATLAS experiment at the LHC. A combined Standard-Model Higgs search using 1.04-4.9 fb^-1 of 7 TeV pp data excluded mH ranges 112.9-115.5 GeV, 131-238 GeV, and 251-466 GeV at 95% CL and observed a 3.5 sigma local excess around 126 GeV, with channel-level local significances of 2.8 (gamma gamma), 2.1 (ZZ*), and 1.4 (WW*) [3]. The ATLAS performance assessment using 2010 7 TeV data included alignment of the inner detector and electromagnetic calorimeter, electron energy scale and resolution determination, response uniformity and linearity, identification and reconstruction efficiencies, and charge-misidentification probability [5]; a parallel paper documented missing-transverse-momentum reconstruction using full event reconstruction and physics-object-based calibration with minimum-bias, jet, Z->ll, and W->l nu samples [7]. The performance of the ATLAS trigger system in 2010 was described, covering identification of muon, electron, photon, tau, jet, B-meson, and global signatures against the 40 MHz LHC bunch-crossing rate [6]. In heavy-ion physics, a centrality-dependent dijet asymmetry was reported in lead-lead collisions at sqrt(s_NN) = 2.76 TeV using fine-grained calorimetry, providing the first observation of jet quenching in PbPb at the LHC [1]. Charged-particle azimuthal anisotropy in lead-lead collisions was characterized by Fourier coefficients v_2-v_6 as functions of pT (0.5-20 GeV), pseudorapidity (|eta| < 2.5), and centrality using an event-plane method, with v_n for n >= 3 varying weakly with eta and centrality [4]. The 2008 "Expected Performance" document compiled simulation-based assessments of track, lepton, photon, missing-energy, and jet reconstruction, b-tagging, trigger, and physics potential for the first LHC operation years [2]. Methodologically the corpus is calorimetric and trigger-based reconstruction in a general-purpose collider detector, applied to electroweak symmetry breaking and quark-gluon-plasma physics.
