相对论性屏蔽势模型对底偶素的预言

Predictions for Bottomonium from a Relativistic Screened Potential Model

Chaitanya Anil Bokade, Bhaghyesh

AI总结:

该研究采用相对论性屏蔽势模型系统计算底偶素的质量谱与衰变性质,并据此判定多个Υ激发态的S-D混合或纯D波归属。

摘要:

在本工作中,利用相对论性屏蔽势模型对底偶素态的质量谱和衰变性质进行了全面分析。研究评估了质量谱、衰变常数、E1跃迁、M1跃迁以及湮灭衰变宽度。文中分析了将Υ(10355)、Υ(10580)、Υ(10860)和Υ(11020)解释为S-D混合底偶素态的方案。Υ(10355)态被认为是3S-2D混合态,Υ(10580)态被认为是4S-3D混合态,Υ(10753)被得到为纯Υ₁(3D)底偶素态,而Υ(10860)和Υ(11020)则被视为5S-4D混合态。

英文摘要:

In this work, a comprehensive analysis of the mass spectra and decay properties of bottomonium states using a relativistic screened potential model is carried out. The mass spectrum, decay constants, $E1$ transitions, $M1$ transitions, and annihilation decay widths are evaluated. The interpretation of $Υ(10355)$, $Υ(10580)$,$Υ(10860)$, and $Υ(11020)$ as $S-D$ mixed bottomonium states are analysed. The $Υ(10355)$ state is considered to be $3S-2D$, $Υ(10580)$ state is considered to be $4S-3D$ mixed state, the $Υ(10753)$ is obtained as purely $Υ_{1}(3D)$ bottomonium state, and the $Υ(10860)$ and $Υ(11020)$ are deemed to be $5S-4D$ mixed states.
