Scientific paper

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.
