Abstract
We discuss the three independent asymmetries, AT(2)(q2), AT(im)(q2) and AT(re)(q2), that one can build from the amplitudes A_perp(q2) and A_par(q2). These quantities are expected to be accessible from the new B-physics experiments, they are sensitive to the presence of new physics, and they are not significantly sensitive to hadronic uncertainties. Studying their low q2-dependence can be helpful in discerning among various possible new physics scenarios. All three asymmetries can be extracted from the full angular analysis of B-->K* l+l-. Our formulas apply to both the massless and the massive lepton case.
