Signatures of Sneutrino NLSP in Gravitino Dark Matter Scenario at the LHC

TL;DR

This paper explores the potential for detecting sneutrino NLSPs in gravitino dark matter models at the LHC, emphasizing leptonic signatures and the viability of trilepton signals as discovery channels.

Contribution

It introduces a detailed phenomenological analysis of sneutrino NLSP scenarios with a focus on leptonic signatures and the potential of trilepton signals for supersymmetry discovery.

Findings

Trilepton signatures can serve as effective discovery channels for sneutrino NLSPs.

Leptonic signatures are promising in identifying supersymmetric models with gravitino dark matter.

Feasibility of detecting sneutrino NLSPs at the LHC is demonstrated.

Abstract

We present the phenomenology of a supersymmetric model with sneutrino as the next to lightest supersymmetric particle (NLSP) in the gravitino dark matter scenario at the LHC. We focus on the leptonic signatures and study the feasibility of a particular trilepton signature as a possible discovery channel of supersymmetry.
