Confronting SUSY models with LHC data via electroweakino production

TL;DR

This paper analyzes how current and future LHC data constrain electroweakino signals in MSSM and TMSSM models, focusing on multi-lepton signatures and their potential to reveal supersymmetric particles.

Contribution

It recasts existing LHC constraints on electroweakinos in MSSM and TMSSM, and forecasts future event rates to aid in identifying supersymmetric origins of multi-lepton signals.

Findings

Wide parameter regions remain allowed by current constraints.

Forecasted event rates will help distinguish supersymmetric models in future data.

Correlations among multi-lepton signals can identify the underlying SUSY model.

Abstract

We investigate multi-lepton signals produced by ElectroWeakino (EWino) decays in the MSSM and the TMSSM scenarios with sfermions, gluinos and non Standard Model Higgses at the TeV scale, being the Bino electroweak-scale dark matter. We recast the present LHC constraints on EWinos for these models and we find that wide MSSM and TMSSM parameter regions prove to be allowed. We forecast the number of events expected in the signal regions of the experimental multi-lepton analyses in the next LHC runs. The correlations among these numbers will help to determine whether future deviations in multi-lepton data are ascribable to the EWinos, as well as the supersymmetric model they originate from.
