| Popis: | 85 We study the branching ratios of the exclusive decays of$B\to K^{(*)}\nu\bar\nu$ and $B\to K^{(*)}\ell^+\ell^-$in various form factors models. We investigate the longitudinal,transverse and normal lepton polarization asymmetries in theexclusive processes of $B\to K\ell^+\ell^-$ and $B\to K^*\ell^+\ell^-$. The T-odd observables arising fromthe two-spin correlation of lepton pair are also evaluated.We include both short and long-distance contributions to theasymmetries in our discussions. It is found that the absorptivepart of the penguin diagram plays an important role in the T-odd quantities. However, these estimations are model dependent. |
