Abstract
We employ the relativistic constituent quark model to give a unified descri ption of the leptonic and semileptonic decays of pseudoscalar mesons (pi, K , D, D-s, B, B-s). The calculated leptonic decay constants and form factors an found to be in good agreement with available experimental data and othe r approaches. We reproduce the results of spin-flavor symmetry in the heavy quark limit. (C) 1999 Published by Elsevier Science B.V, All rights reserv ed.
