Chiral corrections to vector meson decay constants
(1998) In Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics 429(1-2). p.111-120- Abstract
We calculate the leading quark mass corrections of order mqlog(mq), mq and m3/2 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.
