%X The decay B→ K*<i>l</i><sup>+</sup><i>l</i><sup>−</sup> is regarded as one of the most important modes to search for physics beyond the standard model as the angular distribution enables the independent measurement of a plethora of observables. To disentangle new physics from the standard model effect an "exact" test of standard model is needed. This drive us to derive a relation including all short-distance and long-distance effects, factorizable and non-factorizable contributions, complete electromagnetic corrections to hadronic operators up to all orders, resonance contributions and the finite lepton masses in a complete model independent approach. The violation of this relation will provide a smoking gun signal of new physics. The model independent framework has also been implemented in the maximum q<sup>2</sup> limit to highlight strong evidence of right-handed currents, which are absent in the SM. The conclusions derived are free from hadronic corrections. Our approach differs from other approaches that probe new physics at low q<sup>2</sup> as it does not require estimates of hadronic parameters but relies instead on heavy quark symmetries that are reliable at the maximum q<sup>2</sup> kinematic endpoint.
