Completing 1/ m b 3 $$ {m}_b^3 $$ corrections to non-leptonic bottom-to-up-quark decays
Abstract We compute the contributions of dimension six two-quark operators to the non-leptonic decay width of heavy hadrons due to the flavor changing bottom-to-up-quark transition in the heavy quark expansion. Analytical expressions for the Darwin term ρ D and the spin-orbit term ρ LS are obtained...
