Enhancement of the $\Lambda_{b}$ decay rate
The enhancement \Delta \Gamma (\Lambda_b) of the \Lambda_b decay rate due to four-fermion processes of weak scattering and Pauli interference is calculated within the quark model. An estimate of the relative bu wave function at zero separation, |\Psi(0)|^2_{bu}, is obtained in terms of the \Sigma_b^...
