摘要
In supersymmetric models with explicit breaking of R parity the lightest supersymmetric particle (LSP) may be the lightest stau (tau) over tilde (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+/-. We discuss various ways of distinguishing a LSP (tau) over tilde (1) from H+/- at future colliders, and address the case of (tau) over tilde (1) mimicking the signal for H+/-. As an example we suggest that the recent L3 signal for H+H--->qq' qq' and H+H- --> qq' taunu(tau) could be more easily explained by a LSP (tau) over tilde (1).
