Searches for gluinos and squarks

TL;DR

This paper reports on three searches for supersymmetric particles at the LHC, setting new exclusion limits on gluino and squark masses, with no significant excess observed over Standard Model predictions.

Contribution

It presents the most recent experimental limits on gluino and squark masses from multiple search strategies at 13 TeV, extending previous bounds.

Findings

No significant excess observed over Standard Model predictions.

Exclusion limits set for gluino and squark masses up to 2460 GeV.

Disappearing track search extends gluino mass limit to 2460 GeV.

Abstract

Despite the great success of the Standard Model, it still does not explain Dark Matter, matter/antimatter asymmetry and it does not unite the electroweak and the strong forces. As a possible solution, the theory of Supersymmetry was proposed. In this paper, three searches for strong production Supersymmetry are presented. The data correspond to a total integrated luminosity of 137 fb$^{-1}$ at a center-of-mass energy of 13 TeV, recorded at the Large Hadron Collider during the years 2015-2018. There has been no significant excess observed relative to the Standard Model predictions. The data gave the following best 95\% exclusion limits for the masses of squarks and gluinos: 2250 GeV, 1260 GeV and 1225 GeV which are obtained from the inclusive search for gluinos, bottom squarks and top squarks, respectively. The search for disappearing tracks extends the gluino mass limit to as much as 2460 GeV, and the neutralino mass limit to as much as 2000 GeV.
