Other searches at LEP

TL;DR

This paper reviews the LEP collider's 2000 data, presenting new limits on particle production and mass in various beyond Standard Model theories, including supersymmetry, technicolor, and leptoquarks.

Contribution

It provides the first comprehensive set of model-independent and model-specific limits based on LEP's 2000 data at energies up to 209 GeV.

Findings

Model-independent cross-section limits established

Mass bounds set for supersymmetric particles

Constraints placed on technicolor, excited leptons, and leptoquarks

Abstract

During the year 2000, LEP has been operated at centre-of-mass energies up to sqrt(s) = 209 GeV. New particle searches have been performed using these data samples. Model independent limits on the production cross-sections and mass limits in the context of the Minimal Supersymmetric Standard Model (MSSM) assuming R-parity violation and in the context of gauge-mediated supersymmetry breaking theories (GMSB) are presented. Searches for technicolor, excited leptons and leptoquarks are also reviewed.
