Using Tau Polarization to Sharpen up the SUGRA Signal at Tevatron

Abstract

The most promising source of SUGRA signal at the Tevatron collider is the pair-production of electroweak gauginos, followed by their leptonic decay. In the parameter range corresponding to dominant leptonic decay of these gauginos one or more of the leptons are expected to be $\tau$ with $P_{\tau }\simeq +1$. This polarization can be effectively used to distinguish the signal from the background in the 1-prong hadronic decay channel of $\tau$ by looking at the fractional $\tau$-jet momentum carried by the charged prong.
