Cancellation of 1/m_Q Corrections to the Inclusive Decay Width of a Heavy Quark
Abstract
Description
I review the cancellation of non-perturbative 1/m_Q corrections to the heavy quark inclusive decay width. I summarize the results of an explicit second loop order calculation in perturbation theory which shows the absence of linear corrections when the decay width is expressed in terms of the short distance mass.
