Double-lepton polarization asymmetries in the exclusive B ->rho l+l(-) decay beyond the standard model

The double-lepton polarization asymmetries in B ->rho l(+)l(-) decay are analyzed in a model independent framework. The general expressions for nine double-polarization asymmetries are calculated. It is shown that the study of the double-lepton polarization asymmetries proves to be a very useful tool in looking for new physics beyond the standard model.
