Abstract

We study two nonets of excited vector mesons, predominantly corresponding to radially excited vector mesons with quantum numbers n2S+1LJn\hspace{0.08cm} ^{2S+1}L_{J} =23S1=2^3S_1 and to orbitally excited vector mesons with quantum numbers n2S+1LJ=13D1n\hspace{0.08cm} ^{2S+1}L_{J}=1^3D_1. We evaluate two types of decays of these mesons: into two pseudoscalar mesons and into a pseudoscalar and a ground-state vector meson. We compare the results with experimental data taken from PDG. We also make predictions for the strange-antistrange state in the 13D11^3D_1 nonet denoted as ϕ(1930)\phi(1930), which has not yet been discovered.
