Abstract

We discuss an optimal R -parity-breaking SUSY solution to the R b excess as well as the ALEPH four-jet anomaly. The latter arises from the pair production of a top squark via chargino decay at CERN LEP 1.5, followed by its R -violating decay into a light quark pair. The model satisfies top quark and Z -boson decay constraints along with gaugino mass unification.
