Determination of the resonant parameters of excited vector strangenia with the $e^{+}{e}^{-}\to \eta \varphi$ data

Wenjing Zhu, XiaoLong Wang

We determine the resonant parameters of the vector states $\varphi (1680)$ and $\varphi (2170)$, by doing a combined fit to the $e^{+}{e}^{-}\to \eta \varphi$ cross sections from threshold to $2.85\mathrm{GeV}$…
