NMSSM in disguise: discovering singlino dark matter with soft leptons at the LHC

TL;DR

This paper proposes a way to identify a complex NMSSM dark matter scenario at the LHC by detecting soft leptons, revealing its non-minimal nature and measuring key particle mass differences.

Contribution

It introduces a method to distinguish NMSSM from mSUGRA at the LHC through soft lepton detection, highlighting how to reveal the model's non-minimal features.

Findings

Soft leptons can indicate NMSSM scenarios at the LHC.

Bino--singlino mass difference can be measured using soft leptons.

NMSSM can mimic simpler models, complicating detection.

Abstract

We suggest an NMSSM scenario, motivated by dark matter constraints, that may disguise itself as a much simpler mSUGRA scenario at the LHC. We show how its non-minimal nature can be revealed, and the bino--singlino mass difference measured, by looking for soft leptons.
