Abstract

We calculate the leading quark mass corrections of order m_qlog(m_q), m_q and m^3/2 _q to the vector meson decay constants within heavy vector meson chiral perturbation theory. We discuss the issue of electromagnetic gauge invariance and the heavy mass expansion. Reasonably good fits to the observed decay constants are obtained.
