Forward-backward and CP-violating asymmetries in rare B_{d,s}\to (V,\gamma) l^+l^- decays

Abstract

We study the forward-backward and the CP-violating asymmetries (both time-independent and time-dependent) in rare semileptonic $B_d\to {\rho }^0{l}^{+}{l}^{-}$, $B_s\to \varphi l^{+}{l}^{-}$, and radiative leptonic $B_{d,s}\to \gamma l^{+}{l}^{-}$ decays and investigate the sensitivity of these asymmetries to the extensions of the Standard model.

Comments: Revised version: plots for A_CP corrected, discussion of B_d\to \rho^0 l^+l^- added
