摘要：
We present results of a lattice study of the form factors in the decay B --> pi l<(nu)over bar>. We attempt to disentangle the the dependence of the form factors on the light quark masses and the momentum transfer. Using models of the q(2) dependence we calculate the total decay rate, and compare to the experimental measure to extract V-ub This study was performed in the quenched approximation at beta = 6.2 on a 24(3) x 48 lattice, with a non-perturbatively improved SW fermion action.
