Heavy quark expansion for heavy hadron lifetimes: completing the 1 / m b 3 $$ 1/{m}_b^3 $$ corrections

Abstract

Abstract We complete the calculation of the contributions from the dimension six operators in the heavy quark expansion for the total lifetime of heavy hadrons. We give the leading order expressions for the Wilson coefficients of the Darwin term ρ D and the spin-orbit term ρ LS.
