The matrix element of the weak transition {\Lambda}_b\rightarrow{\Lambda}_ccan be expressed in terms of six form factors. {\Lambda}_Q(Q = b;c) can beregarded as composed of a heavy quark Q(Q = b;c) and a diquark which is made upof the remaining two light quarks. In this picture, we express these six formfactors in terms of Bethe-Salpeter wave functions to second order in the 1/m_Qexpansion. With the kernel containing both the scalar confinement and theone-gluon-exchange terms we calculate the form factors and the decay widths ofthe semileptonic decay {\Lambda}_b\rightarrow{\Lambda}_clv as well asnonleptonic decays {\Lambda}_b\rightarrow{\Lambda}_cP(V) numerically. We alsoadd QCD corrections since they are comparable with 1/m_Q corrections.
