Excited states of $\varphi$ meson

Abstract

In this paper, the excited states of $\varphi$ meson, especially containing the newly observed $X(2000)$ with $I(J^P)=0(1^{-})$ by the BESIII Collaboration, is studied. In addition, $Y(2175)$ as a $\varphi$ {\color{black}{meson excited state}} is investigated. The mass spectrum and strong decay behaviors of $\varphi$ {\color{black}{meson excited states}} are analyzed, which indicates that $X(2000)$ and $Y(2175)$ are the candidates of $\varphi (3S)$ and $\varphi (2D)$ states with $I(J^P)=0(1^{-})$, respectively. In addition, {\color{black}{$\varphi (1D)$ and $\varphi (4S)$ are}} predicted to have the mass of 1.87 GeV and 2.5 GeV and width of 550 MeV and 230 MeV, respectively.
