Search for GMSB NLSPs at LHC

TL;DR

This paper reviews strategies developed by ATLAS and CMS over the last decade for detecting long-lived NLSPs in GMSB models at the LHC, addressing challenges posed by their unique decay properties.

Contribution

It summarizes the experimental approaches and detector strategies designed specifically for heavy, semi-stable, or decaying NLSPs in GMSB scenarios at the LHC.

Findings

Effective search strategies have been developed for long-lived NLSPs.

Detectors require special configurations for heavy, semi-stable, or decaying particles.

Recent results improve sensitivity to GMSB NLSP signatures.

Abstract

NLSP - LSP decays could have dramatic influence on SUSY phenomenology at LHC. NLSP could have significant lifetime and could be charged. In at least two scenarios detectors must be used in a special way. They were not optimized for detection of heavy (semi)stable charged particles and decaying in flight (neutral or charged) NLSPs. During the last decade both ATLAS and CMS collaboration have developed strategies which allow for effective search within such scenarios.
