摘要： In supersymmetric models with explicit breaking of R-parity the lightest su-persymmetric particle (LSP) may be the lightest stau, ˜#28;1. Such a scenario would provide a clear sign of R-parity violating SUSY, although its phe-nomenology may resemble that of a charged Higgs boson, H±. We discuss various ways of distinguishing a LSP ˜#28;1 from H± at future colliders, and address the case of ˜#28;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′#28;#23;#28; could be more easily explained by a LSP ˜#28;1.
