ON THE PROBLEM OF BOOSTING NONLEPTONIC B BARYON DECAYS

The constituent picture of hadrons implies certain quantum mechanical inequalities which must hold in the potential models. Based on this qu alitative consideration I argue that it is not easy to significantly i ncrease the scale of the flavour-dependent I/m(b)(3) effects within th e heavy quark expansion while preserving the conventional constituent picture of heavy flavour hadrons. I briefly address the physical conse quences that might be expected if an attempt to push the effects of we ak scattering and interference above the 10% level within 1/m(b) expan sion is made without invoking qualitatively different mechanisms, incl uding violations of duality.
