Semileptonic Form Factors

Abstract

I report the current status of the heavy-light decay constants, the bag parameters and the semileptonic form factors. I compare the heavy-light decay constants with Wilson-Wilson and clover-clover fermions. Systematic errors such as scale setting and renormalization factors are also discussed. 1/M dependences for the heavy-light semileptonic form factors near $q^2=q_m^{2}ax$ with clover-clover and NRQCD-Wilson fermions are found to be small.
