Efforts to predict the rare exclusive decay [ital B][r arrow][ital K][sup *][gamma] from the well-known inclusive decay [ital b][r arrow][ital s][gamma] are frustrated by the effect of the large recoil momentum. We show how to reduce the large uncert

We examine the dilepton energy spectrum for the decay {ital b}{r arrow}{ital sl}{sup +}{ital l{minus}}. The energy spectrum, below the energy of 0.95 GeV, is shown to be more useful than the invariant-mass spectrum for measurements of the top-quark m

In the exclusive decay of the {ital B} meson into a {ital K}{sup *} and a photon, the large recoil momentum creates a difficulty in making a connection between the quark level calculations and the meson states. In the quark model, depending on how th

We look at the problem of QCD mixing between the four-quark operators and the {ital b}{r arrow}{ital s}{gamma} dipole operators in terms of extra {epsilon}-scalar interactions that distinguish the dimensional reduction and the naive dimensional regul
We study the form factors of heavy--to--heavy and heavy--to--light weak decays using the light--front relativistic quark model. For the heavy--to--heavy $B \ra D^{(\ast)}$ semileptonic decays we calculate the corresponding Isgur--Wise function for th
