Abstract

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