Abstract: We present the results of a lattice QCD calculation of the form factor relevant to B→K*γ decay. Our final value, T(0) = 0.24 +/- 0.03 (+0.04/-0.01), is obtained in the quenched approximation, and by extrapolating T(q2=0;H--> K*)MH^(3/2) from the directly accessed H-heavy mesons to the meson B. We also show that the extrapolation from B→K*γ* (q2≠0) to B→K*γ (q2=0), leads to a result consistent with the one quoted above. On the other hand, our results are not accurate enough to solve the SU(3) fla
