On the short distance nonperturbative corrections in heavy quark expansion
Arunagiri, S.
Original · EN
We estimate the renormalon corrections to the inclusive decay rate of heavy hadrons. We assume the gluon mass term λ² ≫ `² to imitate the short distance nonperturbative effects. It is found that the the inclusive decay rates are corrected by an amount of about 0.2 Γ₀ for B meson and 0.21 Γ₀ for baryon. This is significant in view of the discrepancy of lifetimes of B and.
