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 $B_{u,c}^{{ast}{pm}}$.
