Supersymmetry Signatures with Tau Jets at the Tevatron

TL;DR

This paper explores supersymmetry detection at the Tevatron focusing on channels with leptons and tau jets, demonstrating improved search strategies in tau-dominant scenarios with significant potential for extending LEP-II bounds.

Contribution

It introduces a novel search approach combining leptons and tau jets, enhancing supersymmetry detection sensitivity over traditional methods.

Findings

Searches with two leptons, a tau jet, and missing energy outperform classic trilepton searches.

Tevatron can extend LEP-II supersymmetry reach with 4 fb^{-1} of data.

Tau-inclusive channels are promising for supersymmetry discovery.

Abstract

We study the supersymmetry reach of the Tevatron in channels containing both isolated leptons and identified tau jets. In the most challenging case, where the branching ratios of gauginos to taus dominate, we find that searches for two leptons, a tau jet and a large amount of missing transverse energy have a much better reach than the classic trilepton signature. With total integrated luminosity of ${\rm L} \gsim 4 {\rm fb}^{-1}$, the Tevatron will start extending the expected LEP-II reach for supersymmetry.
