Strong and radiative decays of excited vector mesons and predictions for a new $\phi(1930)$ resonance

Understand

We study the phenomenology of two nonets of excited vector mesons, $\{\rho(1450)$, $K^{\ast}(1410)$, $\omega(1420)$, $\phi(1680)\}$ and $\{\rho(1700),$ $K^{\ast}(1680),\omega(1650),$ $\phi(???)\},$ which (roughly) correspond to radially excited $2^{3}S_{1}$ and to orbitally excited $1^{3}D_{1}$ vector mesons.

• We evaluate the strong and radiative decays of these mesons into pseudoscalar and ground-state vector mesons by using an effective relativistic QFT model based on flavour symmetry.
• We compare decay widths and branching ratios with various experimental results listed in the PDG.
• An overall agreement of theory with experiment reinforces the standard quark-antiquark assignment of the resonances mentioned above.
