Search for top squark pair production in final states with one isolated lepton, jets, and missing transverse momentum in 2011 ATLAS data
Dissertation Abstract: 

A cut-and-count search for stop squark pair production in pp collisions at √s = 7 TeVwith 4.71 fb−1 of 2011 ATLAS data is presented. Events with one isolated lepton, four or more jets, and missing transverse energy are selected to study a simplified model of stop squark decay to one top quark and one neutralino χ ̃01. Data is seen to be compatible with Standard Model-only hypothesis, and model-dependent as well as model-independent exclusion limits are set.
