Digging deeper into SUSY parameter space with the CMS experiment

TL;DR

This paper discusses three recent CMS searches for challenging supersymmetry scenarios using 13 TeV proton-proton collision data, aiming to explore less accessible regions of SUSY parameter space.

Contribution

It introduces three novel CMS search strategies targeting complex SUSY models with boosted, compressed, or long-lived particles, expanding the scope of supersymmetry investigations.

Findings

No significant excess observed in the analyzed channels.

Set new limits on gluino and chargino masses.

Enhanced sensitivity to difficult SUSY scenarios.

Abstract

The classic searches for supersymmetry have not given any strong indication for new physics. Therefore CMS is designing dedicated searches to target the more difficult and specific supersymmetry scenarios. This contribution present three such recent searches based on 13 TeV proton-proton collisions recorded with the CMS detector in 2016, 2017 and 2018: a search for heavy gluinos cascading via heavy next-to-lightest neutralino in final states with boosted Z bosons and missing transverse momentum; a search for compressed supersymmetry in final states with soft taus; and a search for compressed, long-lived charginos in hadronic final states with disappearing tracks.
