The poster presents latest results of the search for top squark pair production in final states with one isolated lepton, jets, and missing transverse momentum in $\sqrt s$=8 TeV pp collisions using L=21 fb$^{-1}$ of ATLAS data. Two top squark decay scenarios are considered: (a) to a top quark and a...

description The poster presents latest results of the search for top squark pair production in final states with one isolated lepton, jets, and missing transverse momentum in $\sqrt s$=8 TeV pp collisions using L=21 fb$^{-1}$ of ATLAS data. 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-shell W boson to the LSP. The analysis also employs a new dedicated shape-fit method to target the challenging parameter region where $m$(stop) is close to the kinematic boundary $m$(top) + $m$(LSP).
