Search for anomalous production of prompt like-sign lepton pairs at √s =7 TeV with the ATLAS detector

Georges Aad, +2944 more
- 03 Dec 2012 - 
TL;DR: In this article, an inclusive search for anomalous production of two prompt, isolated leptons with the same electric charge was performed in a data sample corresponding to 4.7 fb(-1) of integrated luminosity collected in 2011 at root s = 7TeV with the ATLAS detector at the LHC.

Search for supersymmetry in events with photons, bottom quarks, and missing transverse momentum in proton-proton collisions at a centre-of-mass energy of 7 TeV with the ATLAS detector

- 26 Feb 2013 - 
TL;DR: In this article, the experimental signature of an isolated photon with high transverse momentum, at least one jet identified as originating from a bottom quark, and high missing transversal momentum was searched using the full dataset of 7 TeV proton-proton collisions recorded with the ATLAS detector at the LHC.

TL;DR: In this paper, the authors used the antikt algorithm with radius parameter R varying between 0.2 and 1.0 to reconstruct the trajectories of the charged particle jets at the Large Hadron Collider (LHC).

Measurement of the inclusive and dijet cross-sections of b-jets in pp collisions at √s = 7 TeV with the ATLAS detector

Georges Aad, +3001 more
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 √ 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 < pT < 400 GeV and rapidity in the range |y| < 2.1. The bb-dijet cross-section is measured as a function of the dijet invariant mass in the range 110 < mjj < 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 crosssections and the predictions obtained using POWHEG + Pythia. MC@NLO + Herwig shows good agreement with the measured bb-dijet cross-section. However, it does not reproduce the measured inclusive cross-section well, particularly for central b-jets with large transverse momenta.
