Abstract

Preliminary results are presented on the calculation of the relevant form factor for the radiative decay B → K^* γ We find that the form factor is weakly dependent on the spectator quark mass. We compare the results obtained for a full chiral extrapolation and where this independence is assumed. Both results are found to be statistically consistent with the experimental data.
