Searches for Gauge Mediated SUSY Breaking at LEP

TL;DR

This paper reports on searches for supersymmetric particles predicted by the GMSB model at LEP, finding no evidence and setting constraints on their properties.

Contribution

It provides the first comprehensive search for neutralinos and sleptons with arbitrary lifetimes within the GMSB framework at LEP energies.

Findings

No evidence for neutralinos or sleptons was observed.

Constraints on production cross-sections and particle masses were established.

Results help refine the parameter space of the GMSB model.

Abstract

Searches for neutralinos and sleptons with arbitrary lifetimes, as predicted in the framework of the Gauge Mediated Supersymmetry Breaking (GMSB) model, have been performed by the four LEP collaborations. No evidence for these particles has been found in the data recorded at center-of-mass energies up to sqrt(s)=209GeV. Therefore constraints on the production cross-sections and particle masses as well as interpretations in the framework of the GMSB model are presented.
