Inclusive search for same-sign dilepton signatures in pp collisions at √s = 7 TeV with the ATLAS detector

Georges Aad, +3069 more
- 01 Jan 2011 - 
TL;DR: In this paper, an inclusive search for new physics in events with two isolated leptons (e or mu) having the same electric charge is presented, and limits are set on the cross-section in a fiducial region for new sources of high-mass dilepton events in the ee, e mu and mu mu channels.
Journal ArticleDOI

Measurement of the top quark pair production cross section in pp collisions at s=7TeV in dilepton final states with ATLAS

Georges Aad, +3024 more
- 07 Feb 2012 - 
TL;DR: A measurement of the production cross section of top quark pairs (ttbar) in proton-proton collisions at a center-of-mass energy of 7 TeV recorded with the ATLAS detector at the Large Hadron Collider is reported in this article.
Journal ArticleDOI

ATLAS measurements of the properties of jets for boosted particle searches

Georges Aad, +2900 more
- 15 Oct 2012 - 
TL;DR: In this article, the properties of high transverse momentum jets, produced in proton-proton collisions at a center-of-mass energy of root s = 7 TeV, were compared to the expectations of Monte Carlo generators that match leading-logarithmic parton showers to leading-order or next-to-leading-order, matrix elements.
Journal ArticleDOI

A search for flavour changing neutral currents in top-quark decays in $pp$ collision data collected with the ATLAS detector at $s=7$ TeV

Georges Aad, +2896 more
- 28 Sep 2012 - 
TL;DR: In this article, a search for flavour changing neutral current (FCNC) processes in top-quark decays by the ATLAS Collaboration is presented, with one top quark decaying through the t -> Zq FCNC (q = u, c) channel, and the other through the Standard Model dominant mode t -> Wb.
Journal ArticleDOI

- 22 Oct 2012 -
