Abstract
decay as mediated by is studied in a modified fermion-loop model. The effect of is simulated by a phenomenologically constructed parity-violating meson-baryon-baryon interaction without introducing any new parameters. We find that the predicted branching ratio is of the same order of magnitude as that of the tree-graph model of Moshe and Singer.
