Scalar tau Signal at LEP 2 in models with Gauge Mediated Supersymmetry Breaking

Abstract

In theories with gauge mediated supersymmetry breaking, the scalar tau, (${\tilde{\tau }}_1$) is the lightest observable superpartner for part of the parameter space. At LEP 2, the production of such a ${\tilde{\tau }}_1$ pair and their subsequent decays give rise to a pair of $\tau$ leptons plus missing energy from the unobserved gravitinos. The angular distributions of the $\tau$'s are different from those arising from the production and decay of W pairs, and thus will constitute an interesting signal for supersymmetry. We also consider ${\tilde{\tau }}_1$ pair production in the complementary part of parameter space where the lightest neutralino is lighter than the ${\tilde{\tau }}_1$.
