The analysis of $B_{d}\rightarrow (\eta, \eta^{{'}})\ell^+\ell^-$ decays in the standard model

Abstract.

We study the differential branching ratio, the branching ratio and the CP-violating asymmetry for the exclusive $B_{d}\to (\eta,\eta^{'})\ell^+\ell^-$ decays in the standard model. We deduce the $B_{d}\to (\eta, \eta^{{'}})$ form factors from the form factors of $B \to \pi$ available in the literature, by using the SU(3) _F symmetry. We observe that these decay modes, which are within the reach of forthcoming B-factories, are very promising for observing CP-violation.
