The notion of resonance matrix elements is discussed. The analogue of the Lellouch-Lüscher formula for the pion photo(electro)production amplitude in the Δ(1232) resonance region is given. A prescription for the pole extraction of the ΔNγ* transition form factors is provided. Theoretical prospects on the lattice calculation of B → K*(892)l+l− form factors are briefly summarized.
