Squark/gluino searches in hadronic channels with CMS

TL;DR

This paper reports on four CMS analyses searching for squarks and gluinos in hadronic final states with missing transverse momentum, setting new limits on their masses and production cross sections at 13 TeV.

Contribution

It introduces four novel analysis techniques using different kinematic variables to improve sensitivity in squark and gluino searches at the LHC.

Findings

No significant deviation from the Standard Model observed.

Extended exclusion limits on squark and gluino masses.

Improved sensitivity over previous results.

Abstract

These proceedings summarize the results of four analyses which searched for squarks and gluinos in hadronic final states with missing transverse momentum in 2.3 fb$^{-1}$ of data in proton-proton collisions at $\sqrt{s}=13$ TeV collected in the year 2015 with the CMS detector at the CERN LHC. Each analysis is characterized by a different kinematic variable that is sensitive to the presence of invisible particles, e.g., $M_\text{T2}$, $\alpha_{\text{T}}$, and razor variables. We observed no significant deviation from the standard model prediction and placed limits on the production cross sections and the masses of squarks and gluinos in simplified models of supersymmetric models. The limits are significantly extended from the previous results.
