Studying the sensitivity of monotop probes to compressed supersymmetric scenarios at the LHC

TL;DR

This paper evaluates the potential of monotop signatures at the LHC to detect compressed supersymmetric scenarios, focusing on small mass splittings and comparing with traditional search methods.

Contribution

It introduces analysis strategies for monotop probes sensitive to compressed SUSY regions and compares their reach with existing LHC search techniques.

Findings

Monotop probes can access regions with small superparticle mass splittings.

Strategies are effective for both leptonic and hadronic monotop decays.

Monotop searches complement traditional SUSY search methods.

Abstract

We investigate the sensitivity of the Large Hadron Collider to supersymmetric setups using monotop probes in which the signal is a single top quark produced in association with missing transverse energy. Our prospective study relies on Monte Carlo simulations of 300 invfb of proton- proton collisions at a centre-of-mass energy of 14 TeV and considers both leptonic and hadronic monotop decays. We present analysis strategies sensitive to regions of the supersymmetric parameter space which feature small superparticle mass splittings and illustrate their strengths in the context of a particular set of benchmark scenarios. Finally, we compare the regions of parameter space expected to be accessible with monotops probes during the next run of the LHC to the reach of more traditional search strategies employed by the ATLAS and CMS collaborations, where available.
