Dilepton Mass Endpoint in the NMSSM

TL;DR

This paper explores NMSSM scenarios to explain an excess in dilepton mass distribution observed by CMS, highlighting their unique features that distinguish them from MSSM in LHC and detection experiments.

Contribution

It demonstrates that NMSSM models can account for the CMS dilepton excess and are distinguishable from MSSM in current and future experiments.

Findings

NMSSM can explain the CMS dilepton excess

NMSSM features differ from MSSM in collider signatures

Distinct detection prospects for NMSSM and MSSM

Abstract

NMSSM scenarios are investigated to explain an excess in the opposite-sign dilepton mass distribution in events with dilepton, jets and missing transverse energy reported by the CMS experiment. We show that the NMSSM scenarios can possess unique features to explain this excess, and can be distinguished from the MSSM scenarios in the ongoing LHC runs as well as direct detection experiments.
