Heavy Quark Expansion for Heavy Hadron Lifetimes: Completing the $1/m_b^3$ Corrections

High Energy Physics - Phenomenology 2024-06-18 v3

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 expressions for the Wilson coefficients of the Darwin term ρD\rho_D and the spin-orbit term ρLS\rho_{\rm LS} at tree level.
