摘要：

We present a method to compute, by numerical simulations of lattice QCD, the light-cone wave functions which enter exclusive processes at large momentum transfer, such as electromagnetic elastic scatterings, or exclusive semi-leptonic decays as B --> pi (B --> rho) and radiative decays as B --> K*gamma. The method is based on first principles and does not require any model assumption. (C) 1998 Published by Elsevier Science B.V. All rights reserved.
