Inclusive searches for squarks and gluinos with the ATLAS detector

Abstract

Searches for squarks and gluinos in final states with high-pT jets, missing transverse momentum, electrons, muons, taus and photons are presented. The data were recorded in 2012 by the ATLAS experiment in √s = 8 TeV proton-proton collisions at the Large Hadron Collider, with a total integrated luminosity of 20.3 fb−1. No significant excess above the Standard Model expectation is observed. Results are interpreted in a variety of simplified and specific supersymmetry models assuming that R-parity is conserved with the lightest supersymmetric particle being a neutralino or a gravitino. These limits extend the region of supersymmetric parameter space excluded by previous searches at the Large Hadron Collider.
