Spectator Effects in Inclusive Decays of Beauty Hadrons


We present a model-independent study of spectator effects, which are responsible for the lifetime differences between beauty hadrons. These effects can be parametrized in terms of hadronic matrix elements of four four-quark operators. For B mesons, the coefficients of the non-factorizable operators turn out to be a factor 10–100 larger than those of the… (More)
