Exclusive versus Inclusive Semileptonic $\bar{B}$ Decays in the Quark Model

Abstract

Some emerging difficulties in the theoretical description of exclusive semileptonic $\bar{B}$ decays are discussed in the context of the quark model. While there are no unambiguous problems at this time, I discuss physics beyond the valence quark model which should eventually be probed by precision measurements of $\bar{B}$ semileptonic decays.
