Search for direct top squark pair production in final states with one electron or muon using 21 fb−1 of ATLAS data

This article presents latest results of the search for top squark pair production in final states with one isolated lepton, jets, and missing transverse momentum in √s = 8 TeV pp collisions using L=21 fb−1 of data recorded with the ATLAS detector at the LHC. Two top squark decay scenarios are consid...

description This article presents latest results of the search for top squark pair production in final states with one isolated lepton, jets, and missing transverse momentum in √s = 8 TeV pp collisions using L=21 fb−1 of data recorded with the ATLAS detector at the LHC. Two top squark decay scenarios are considered: (a) to a top quark and a long-lived undetected neutral particle (LSP), (b) to a bottom quark and a chargino, where the chargino decays via an on- or off-shellWboson to the LSP. The analysis also employs a new dedicated shape-fit method to target the challenging parameter region where m(t¯)$m(ar t)$ is close to the kinematic boundary m(t) +m(LS P).
