Abstract

The relativistic quark potential model (QPM) is developed for describingvector mesons and their leptonic decays. The new representation Salpeter equation for vector mesons is proposed. Studying the τ→ρν decay theexpression for ρ-meson leptonic decay constant f_ρ isobtained. It is shown that quark model describes on a satisfactory level both theconstant f_ρ and the masses of other charged vector mesons. Thevalues for the leptonic decay constants of K^*,D^*,D^*_s,B^*,B^*_c mesons are predicted.
