On the Problem of Boosting Nonleptonic b Baryon Decays

Abstract

The constituent picture of hadrons implies certain quantum mechanical inequalities which must hold in the potential models. Basing on this qualitative consideration I argue that it is not easy to increase significantly the scale of the flavor-dependent 1/m_b^3 effects within the heavy quark expansion preserving the conventional constituent picture of heavy flavor hadrons. I briefly address the physical consequences one might expect if the effects of weak scattering and interference are attempted to be pushed above the 10% level within 1/m_b expansion not invoking qualitatively different mechanisms including violations of duality.

8 pages, one figure. LaTeX. Revised: More general inequality is stated which applies to <p^4> in baryons as well. Explicit expression for the hybrid renormalization used is quoted
