An R-Parity Breaking SUSY Solution to the R_b and ALEPH Anomalies
arXiv:hep-ph/9608264 · doi:10.1103/PhysRevD.54.6797
Abstract
We discuss an optimal $R$-parity breaking SUSY solution to the $R_b$ excess as well as the ALEPH 4-jet anomaly. The latter arises from the pair production of stop via chargino decay at LEP1.5, 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.
