Description
We study the decays of two nonets of excited vector mesons which predominantly correspond to $n \hspace{0.15cm} ^{2s+1}L_J = 2 ^{3}S_{1}$ (radially excited vector mesons) and $n \hspace{0.15cm}^{2s+1}L_J = 1 ^{3}D_{1}$ (angular-momentum excited vector mesons). By using a quantum field theoretical approach we evoluate the decay widths of these mesons into two pseudoscalar mesons and into pseudoscalar and ground-state vector mesons. Moreover by introducing vector meson dominance we study radiative decays of excited vector mesons into a photon and a pseudoscalar meson. We compare our results with the experimental data from PDG. We also make predictions for an unkown $s\bar{s}$ state in $1 ^{3}D_1$ nonet, that we call $\phi(1930)$. This state was not yet discovered but can be found in the upcoming Gluex and Mesonex experiments at Jefferson lab.
