Unveiling stealth SUSY in the low missing energy terrain at the LHC

Abstract

Using a set of missing energy-independent selection criteria involving large-radius jet multiplicity and angular separation among the final states, we extend the discovery potential of the stealth SUSY squark-pair production in the low missing transverse energy (ETmiss) parameter space, thereby complementing existing ATLAS and CMS searches that are sensitive in the high ETmiss regime. With these kinematic cuts, the estimated sensitivity was extended to squark masses up to 2500 GeV for a bino mass of 650 GeV.
