Strong decays of excited vector mesons

Abstract

We study two nonets of excited vector mesons, predominantly corresponding to radially excited vector mesons with quantum numbers $n{}^{2S+1}{L}_J$ $=2^3{S}_1$ and to orbitally excited vector mesons with quantum numbers $n{}^{2S+1}{L}_J=1^3{D}_1$. 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 $1^3{D}_1$ nonet denoted as $\varphi (1930)$, which has not yet been discovered.
