Search for R-parity Violating Decays of Supersymmetric Particles in e+e- Collisions at LEP

TL;DR

This paper reports a search for R-parity violating decays of supersymmetric particles in electron-positron collisions at LEP, setting new limits on their production and masses without observing any signal.

Contribution

It introduces a search method for supersymmetric particles assuming single non-negligible R-parity violating couplings, extending previous analyses.

Findings

No evidence of supersymmetric particle production was observed.

Limits on cross sections and masses were established.

The results constrain R-parity violating SUSY models.

Abstract

A search, in e^+e^- collisions, for chargino, neutralino, scalar lepton and scalar quark pair-production is performed, without assuming R-parity conservation in decays, in the case that only one of the coupling constants lambda_ijk or lambda''_ijk is non-negligible. No signal is found in data up to a centre-of-mass energy of 208GeV. Limits on the production cross sections and on the masses of supersymmetric particles are derived.
