Statistical combination of all-hadronic and one-lepton analyses targeting scalar top pair production using proton-proton collisions at √ s = 8 TeV with the ATLAS detector

A statistical combination of two analyses targeting direct stop pair production and requiring respectively no leptons and one lepton in the final state is presented. The observed exclusion limit on the stop mass for a small neutralino mass in a scenario where the stop is assumed to decay only into t...

description A statistical combination of two analyses targeting direct stop pair production and requiring respectively no leptons and one lepton in the final state is presented. The observed exclusion limit on the stop mass for a small neutralino mass in a scenario where the stop is assumed to decay only into t ̃ → t χ ̃01 is 700 GeV. This is an increase by about 50 GeV with respect to the limits obtained by the individual analyses. Limits are also presented when varying the branching fraction between the stop decaying byt ̃1 →tχ ̃01 andt ̃1 →bχ ̃±1.
