$ϕ$介子的激发态

Excited states of $ϕ$ meson

Cheng-qun Pang

摘要:

本文研究了$ϕ$介子的激发态,特别是BESIII合作组新观测到的含$I(J^P)=0(1^-)$的$ϕ$介子的激发态。此外,研究了作为$ϕ$ { \color{black}{meson excited state} }的$Y(2175)$。分析了$ϕ$ { \color{black}{meson excited states} }的质谱和强衰变行为,表明$X(2000)$和$Y(2175)$分别是$ϕ(3S)$和$ϕ(2D)$与$I(J^P)=0(1^-)$的候选态.此外,{ \color{black}{$ϕ(1D)$ and $ϕ(4S)$ are} }预测的质量分别为1.87 GeV和2.5 GeV,宽度分别为550 MeV和230 MeV。

英文摘要:

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