Search for gluinos in events with an isolated lepton, jets and missing transverse momentum at √s = 13 TeV with the ATLAS detector

The results of a search for gluinos in final states with an isolated electron or muon, multiple jets and large missing transversemomentum using proton–proton collision data at a centre-of-mass energy of √s = 13 TeV are presented. The dataset usedwas recorded in 2015 by theATLAS experiment at the Lar...

Sumario:The results of a search for gluinos in final states with an isolated electron or muon, multiple jets and large missing transversemomentum using proton–proton collision data at a centre-of-mass energy of √s = 13 TeV are presented. The dataset usedwas recorded in 2015 by theATLAS experiment at the Large Hadron Collider and corresponds to an integrated luminosity of 3.2 fb<sup>−1</sup>. Six signal selections are defined that best exploit the signal characteristics. The data agree with the Standard Model background expectation in all six signal selections, and the largest deviation is a 2.1 standard deviation excess. The results are interpreted in a simplified model where pair-produced gluinos decay via the lightest chargino to the lightest neutralino. In this model, gluinos are excluded up to masses of approximately 1.6 TeV depending on the mass spectrum of the simplified model, thus surpassing the limits of previous searches.
