Beyond the Standard Model at Tevatron

Abstract

This article presents recent results of searches for physics beyond the Standard Model using the CDF and the D$\not$O detector at the Fermilab Tevatron Collider. All results shown correspond to analysis performed using the past 1992-1996 Fermilab Tevatron run I data (roughly $100$ $pb^{-1}$ per each experiment). In particular we describe recent Tevatron searches for scalar top in the $b+\ell+$missing-$E_{T}$ channel, for squark and gluinos using like-sign dileptons (LS), for large extra space-time dimensions and the search for leptoquarks and technicolor in the missing-$E_{T}$+heavy flavour jet events. Tight limits on the existence of such models have been set.
