抄録

We examine several asymmetries which are considerable in the rare b→d decays. The paper is focused on the semi-leptonic B→X_dl^+l^- decay. It is shown that CP-violation factor in the process gives non-trivial behaviour in the CP and lepton polarization asymmetries, but does not in the decay distribution and forward-backward asymmetry.
