Update of the search for supersymmetric particles in scenarios with Gravitino LSP and Sleptons NLSP

TL;DR

This paper updates the search for supersymmetric particles like sleptons, neutralinos, and charginos in scenarios with gravitino as the LSP, providing new mass limits based on 1999 DELPHI data.

Contribution

It presents the latest experimental limits on supersymmetric particles in gravitino LSP scenarios using data from the DELPHI detector.

Findings

No evidence for supersymmetric particle production was observed.

New mass exclusion limits were established at 95% confidence level.

Analysis covered center-of-mass energies around 192-202 GeV.

Abstract

An update of the search for sleptons, neutralinos and charginos in the context of scenarios where the lightest supersymmetric particle is the gravitino and the next-to-lightest supersymmetric particle is a slepton, is presented, together with the update of the search for heavy stable charged particles in light gravitino scenarios and Minimal Supersymmetric Standard Models. Data collected in 1999 with the DELPHI detector at centre-of-mass energies around 192, 196, 200 and 202 GeV were analysed. No evidence for the production of these supersymmetric particles was found. Hence, new mass limits were derived at 95% confidence level.
