Scientific paper

A detailed discussion based on exact calculations, possible in the non
relativistic quark model, is given to show that there is no 1/m_Q term in the
heavy quark expansion of totally integrated semileptonic decay rates. More
generally, it is shown that OPE holds with very few terms in the expansion, at
least in the harmonic oscillator model.
