Observation of Spin Correlation in tt̄ Events from pp Collisions at √s = 7 TeV Using the ATLAS Detector
(American Physical Society, 2012-05-24)
A measurement of spin correlation in tt̅ production is reported using data collected with the ATLAS detector at the LHC, corresponding to an integrated luminosity of 2.1 fb⁻¹. Candidate events are selected in the dilepton ...
Search for a Supersymmetric Partner to the Top Quark in Final States with Jets and Missing Transverse Momentum at √s̅ = 7TeV with the ATLAS Detector
(American Physical Society, 2012-11-20)
A search for direct pair production of supersymmetric top squarks (t 1) is presented, assuming the t1 decays into a top quark and the lightest supersymmetric particle, χ10, and that both top quarks decay to purely hadronic ...
