Could the be substantially different from and in the supersymmetric standard model?
R-parity stands as an ad hoc assumption in the most popular version of the
supersymmetric standard model. More than fifteen years' studies of R-parity
violations have been restricted to various limiting scenarios. We illustrate
how the single-VEV parametrization provides a workable framework to analyze the
phenomenology of the complete theory of supersymmetry without R-parity. In our
comprehensive study of various aspects of the resulting leptonic phenomenology
at tree-level, we find that the physical lepton could actually bear
substantial gaugino and higgsino components, making it very different from the
