Abstract:

In experiment with the SND detector at the VEPP-2M ${e}^{+}{e}^{\ensuremath{-}}$ collider the ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\ensuremath{\eta}\ensuremath{\gamma}$ cross section was measured in the center-of-mass energy range $E=0.60--1.38\text{ }\text{ }\mathrm{GeV}$ with the integrated luminosity of $27.8\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$. The measured cross section is well described by the vector meson dominance model with contributions from the $\ensuremath{\rho}(770)$, $\ensuremath{\omega}(783)$, $\ensuremath{\phi}(1020)$, ${\ensuremath{\rho}}^{\ensuremath{'}}(1465)$ resonances and agrees with results of previous measurements. The decay probabilities $\mathcal{B}(\ensuremath{\phi}\ensuremath{\rightarrow}\ensuremath{\eta}\ensuremath{\gamma})$, $\mathcal{B}(\ensuremath{\omega}\ensuremath{\rightarrow}\ensuremath{\eta}\ensuremath{\gamma})$ and $\mathcal{B}(\ensuremath{\rho}\ensuremath{\rightarrow}\ensuremath{\eta}\ensuremath{\gamma})$ were measured with the accuracies better than or comparable to the world averages.

Study of the $ω$/$ω_3$, $ρ$/$ρ_3$ and the newly observed $ω$-like state $X(2220)$

We study the excited states of $ω$ and $ω_3$ by comparison with the $ρ$ and $ρ_3$ families, and discuss the possibility of $X(2220)$ as $ω$ excitation by analyzing the mass spectra and strong decay behaviors. In addition, we predict the masses and widths of $ω(2D)$ and $ω_3$and $ρ_3(4D)$, $ρ_3(1G)$, $ω_3$ and $ρ_3(2G)$ and $ω_3(3G)$ and $ρ_3(3G)$. The abundant information of their two-body strong decays predicted in this work will be helpful to further study of these $ω$ and $ω_3$ and $ρ$ and $ρ_3$ states in experiment and theory.
