Provides constraints on new physics models.

Abstract

Results from BABAR's full dataset are presented for the angular analysis of the rare decay B -> K*l+l-, where l represents an electron or muon, including measurements of the longitudinal K* polarization and the lepton forward-backward asymmetry.
