Abstract
The results of a search for squarks and gluinos in final states with an isolated electron or muon, multiple jets and large missing transverse momentum using proton--proton collision data at a center-of-mass energy of $\sqrt{s}$ = 13 TeV are presented. The dataset used was recorded during 2015 and 2016 by the ATLAS experiment at the Large Hadron Collider and corresponds to an integrated luminosity of 36.1 $fb^{-1}$. No significant excess beyond the expected background is found. Exclusion limits at 95% confidence level are set in a number of supersymmetric scenarios, reaching masses up to 2.1 TeV for gluino pair production and up to 1.25 TeV for squark pair production.
Highlights
Supersymmetry (SUSY) [1,2,3,4,5,6] is a theoretical framework of physics beyond the Standard Model (SM) which predicts for each SM particle the existence of a supersymmetric partner differing by half a unit of spin
In R-parity-conserving SUSY [13], gluinos or squarks are pair produced at the Large Hadron Collider (LHC) via the strong interaction and decay either directly or via intermediate states to the lightest supersymmetric particle (LSP)
The analysis extends previous ATLAS searches with similar event selections performed with data collected in 2010
Summary
Supersymmetry (SUSY) [1,2,3,4,5,6] is a theoretical framework of physics beyond the Standard Model (SM) which predicts for each SM particle the existence of a supersymmetric partner (sparticle) differing by half a unit of spin. In R-parity-conserving SUSY [13], gluinos or squarks are pair produced at the Large Hadron Collider (LHC) via the strong interaction and decay either directly or via intermediate states to the lightest supersymmetric particle (LSP). Four SUSY models with gluino or squark pair production and different decay topologies are considered. The first two models, referred to as the gluino and squark one-step models for the rest of this paper, are SUSY simplified models [18,19,20] in which pair-produced gluinos or squarks decay via the lightest chargino In the MSSM this decay chain is realized when the gluino decays, via a virtual squark that is the partner particle of the left-handed SM quark, to the chargino with a dominant wino component.
