The decay widths of V→K(π)lν¯l are calculated within the Nambu–Jona-Lasinio model, where V=K∗,ρ,ω,ϕ and l=μ,e. The results are obtained using the previously fixed model parameters without introducing any arbitrary parameters. The obtained results are considered as predictions due to the absence of experimental data.
