Search for supersymmetry in events involving third generation squarks and sleptons with ATLAS

摘要

Supersymmetry with large mixing between left and right scalar fermions predicts that the lightest partners of the SM fermions belong to the third generation. Moreover, naturalness arguments favour stop masses not too far from that of the top quark. This document presents results from searches for gluino mediated sbottom and stop production, direct sbottom and stop production, and gluino and squark mediated stau production using data recorded in proton-proton collisions at √s = 7 TeV with the ATLAS detector at the LHC in 2011.
