Calculation of 1/m^{2}_{b} corrections to Λ_b\rightarrowΛ_c decay widths in the Bethe-Salpeter equation approach

L. Zhang, X. -H. Guo, M. -H. Weng

The matrix element of the weak transition Λ_b\rightarrowΛ_c can be expressed in terms of six form factors. Λ_Q(Q = b;c) can be regarded as composed of a heavy quark Q(Q = b;c) and…
