Abstract

We compute the contributions of dimension six two-quark operators to the\nnon-leptonic decay width of heavy hadrons due to the flavor changing\nbottom-to-up-quark transition in the heavy quark expansion. Analytical\nexpressions for the Darwin term \ρ_D and the spin-orbit term \ρ _rm\nLS are obtained with leading order accuracy.\n
