摘要：

We calculate the leading quark mass corrections of order m(q)log(m(q)), m(q) and m(q)(3/2) 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. (C) 1998 Elsevier Science B.V.
