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

  1. Comparing relativistic and non-relativistic quark pair creation models

    hep-ph 2026-04 unverdicted novelty 4.0

    Relativistic and non-relativistic QPC models produce strong decay width predictions of similar overall quality for light mesons, with the relativistic version exhibiting stronger suppression at high energies.

  2. Fully-strange tetraquarks: fall-apart decays and experimental candidates

    hep-ph 2026-01 unverdicted novelty 4.0

    Fully-strange tetraquarks mostly show narrow fall-apart decay widths of O(10) MeV, with X(2300) possibly matching the 1S-wave 1^{+-} state at 2323 MeV and X(2500) the 1P-wave 0^{-+} state at 2481 MeV.
