Purely leptonic decays of the ground charged vector mesons

Inspired by the potential prospects of LHCb, Belle-II, STCF, CEPC and FCC-ee experiments, we discussed the probabilities of experimental investigation on the purely leptonic decays of the ground charged vector mesons including ${\rho}^{\pm}$, $K^{{\ast}{\pm}}$, $D_{d,s}^{{\ast}{\pm}}$ and $B_{u,c}^{{\ast}{\pm}}$.
