Abstract

We use a QCD relativistic potential model to compute the strong coupling constant g appearing in the effective Lagrangian which describes the interaction of 0^- and 1^- q Q states with soft pions in the limit m_Q → ∞. We compare our results with other approaches; in particular, in the non relativistic limit, we are able to reproduce the constituent quark model result: g=1, while the inclusion of relativistic effects due to the light quark gives g=1 \over 3, in agreement with QCD sum rules. We also estimate heavy meson radiative decay rates, with results in agreement with available experimental data.
