B => D(*) transitions in a quark model

Abstract

We propose a constituent quark model to evaluate heavy decay constants and form factors relevant for B=>D(*) semileptonic transitions. We show that the model reproduces the scaling laws dictated by the spin-flavour symmetry in the heavy quark limit and describes quite well the experimental data.
