Stau LSP and comparison with H^+(-) phenomenology

Abstract

In supersymmetric models with explicit breaking of R-parity the lightest supersymmetric particle (LSP) may be the lightest stau, $\stau_1$. Such a scenario would provide a clear sign of R-parity violating SUSY, although its phenomenology may resemble that of a charged Higgs boson, $H^{\pm }$. We discuss various ways of distinguishing a LSP $\stau_1$ from $H^{\pm }$ at future colliders, and address the case of $\stau_1$ mimicking the signal for $H^{\pm }$. As an example we suggest that the recent L3 signal for $H^{+}{H}^{-}\to q{q}^{\prime }q{q}^{\prime }$ and $H^{+}{H}^{-}\to q{q}^{\prime }\tau {\nu }_{\tau }$ could be more easily explained by a LSP $\stau_1$.
