We discuss a generalization of the Lüscher approach to the calculation of the matrix elements of the unstable states. A theoretical framework for the lattice extraction of the ΔNγ
* transition form factors is formulated. The procedure to measure the form factors at the resonance pole is given. The current theoretical progress on the B→K* γ* decays is briefly summarized. [ABSTRACT FROM AUTHOR]- Published
