Lattice results for Heavy-Light matrix elements

Abstract

We review recent lattice computations relevant for $D$ and $B$ decays. Decay constants $f_{D,D_s}$, $f_{B,B_s}$, $D\to K(K^{\ast })$, $B\to \pi ,\rho$ semi-leptonic form factors together with the slope of the Isgur-Wise function calculations are presented. Some recent results of $B\to K^{\ast }\gamma$ form factors will be given. $1/M$ corrections to the asymptotic scaling laws are discussed.
