Abstract

We use a sample of 384×106 BB̄ events collected with the BABAR detector at the PEP-II e+e- collider to study angular distributions in the rare decays B→K* + -, where + - is either e+e- or μ+μ-. For low dilepton invariant masses, m [removed]3.2GeV/c2, we measure AFB=0.76-0.32+0.52±0.07 and FL=0.71-0.22+0.20±0.04.
