Flavor changing interactions of the gluino allow the $b$ quark to decay into the strange quark plus a gluino pair if the gluino is in the ultra low mass window below 1 GeV. In this case the enhancement of the nonleptonic $b$ decay could explain the anomalous semileptonic branching ratio.
We investigate the possibility that the difference between the measurements of $α_3(M_Z)$ from the hadronic branching ratio of the $Z^0$ and the world average of other measurements is due to the decay of the $Z^0$ into quark, anti-squark, and gluino. Consequences for supersymmetry breaking models are discussed.
