Preasymptotic effects in beauty decays
Large preasymptotic effects in beauty decays have been found using heavy-quark and SU(3) symmetry, as well as experimental data on charmed hyperons. Contrary to rather uniform beauty-meson lifetimes, a much larger spread of beauty-baryon lifetimes is predicted. However, it is highly unlikely that, theoretically, the the τ(Λb)/τ(B0d) ratio, which at present deviates more than 1 sigma from the experimental result, can be lowered below 0.9.
