Abstract

The polarized lepton pair forward-backward asymmetries in B\ensuremath→\ensuremathρ\ensuremathℓ⁺\ensuremathℓ^\ensuremath- decay using a general, model independent form of the four-Fermi interaction is studied. The general expressions for nine double-lepton polarization forward-backward asymmetries are calculated. The study of the forward-backward asymmetries of the doubly polarized lepton pair proves to be a very useful tool in looking for new physics beyond the standard model.
