Search for squarks and gluinos with the ATLAS detector in final states with jets and missing transverse momentum using 20.3 $fb^{-1}$ of $\sqrt{s}$ = 8 TeV proton-proton collision data

TL;DR

This paper reports on a search for supersymmetric squarks and gluinos using 8 TeV proton-proton collision data from the ATLAS detector, focusing on events with jets and missing transverse momentum to find evidence of new heavy particles.

Contribution

It presents the first comprehensive search for squarks and gluinos in jets plus missing energy final states using the full 2012 ATLAS dataset at 8 TeV.

Findings

No significant excess observed over Standard Model predictions

Sets new exclusion limits on squark and gluino masses

Improves constraints on supersymmetric models

Abstract

Weak scale supersymmetry is one of the best motivated and studied Standard Model extensions. It predicts the existence of new heavy coloured particles called squarks and gluinos which are the supersymmetric partners of the quarks and gluons, respectively. The poster summarises results on inclusive searches for supersymmetric squarks and gluinos in events containing jets and missing transverse momentum without leptons. The searches use the full data sample recorded in 2012 at $\sqrt{s}$=8~TeV centre-of-mass energy by the ATLAS experiment at the LHC.
