Stop and sbottom searches at LEP

Abstract

This talk reviews the searches for sbottom and stop quarks at LEP. The existing results of the four LEP experiments for sbottom and stop quarks searches are summarized. Furthermore, new mass limits on stable hadronizing squarks and gluinos are derived by combining Z-lineshape constraints with direct searches for squarks and gluinos using ALEPH data. All limits are derived in the framework of R-parity conserving models.Comment: 4 pages, 7 figures.
