- W1676620144 abstract "The difference of tau (B) and tau (Lambdab) indicates the role of the light flavors. We calculate the lifetimes of B-meson and hb based on the weak effective Hamiltonian while assuming the heavy baryon is constructed by a heavy b-quark and a diquark containing two light quarks. In this scenario, we use the information of the measured ratio tau (Lambdab)/tau (B) as input to predict rates of the inclusive weak decays of Sigma (()(b)*()) and Xi (()(b)*()) into non-bottom final states. We find that these rates of Sigma (()(b)*()) and Xi (()(b)*()) are much larger than those of B-mesons and Lambda (b). We also give the predictions for the lifetimes of Omega (b) and Omega (b)*. Phenomenological implication of our result is discussed." @default.
