Abstract
Lattice efforts to compute matrix elements relevant to semi-leptonic form factors are reviewed. The emphasis is on D → K* where the two groups seem to find appreciably different results for A2(0)/A1(0). Lattice measurements at the end-point region for both the 0- and the 1- final states are emphasized. All the lattice results seem to suggest that for D, Ds decays to 1- final states, the A1 form factor at the endpoint is always close to unity. We note that the FNAL experiment E691 does not agree with lattice results for A1 at the endpoint; in addition it tends to disagree with our value for A2(0)/A1(0).
