摘要:

本文在组分夸克模型框架内对隐粲分子五夸克态的电磁性质进行了系统研究。具体聚焦于两类五夸克态:具有双重奇异数的 $Ξ_c^{(\prime,*)} \bar{D}_s^{*}$ 型五夸克态和具有三重奇异数的 $Ω_{c}^{(*)}\bar D_s^{*}$ 型五夸克态。研究探讨了多种电磁性质,包括这些五夸克态的磁矩、跃迁磁矩以及辐射衰变行为。为确保计算的现实性,考虑了 $S$-$D$ 波混合效应和耦合道效应。通过考察具有双重和三重奇异数的隐粲分子五夸克态的电磁性质,本研究有助于更深入地理解它们的光谱行为。这些发现为正在进行的关于隐粲分子五夸克态更广泛性质谱的研究提供了有价值的补充。

英文摘要:

This paper presents a systematic investigation of the electromagnetic properties of the hidden-charm molecular pentaquarks within the constituent quark model. Specifically, it focuses on two types of pentaquarks: the $Ξ_c^{(\prime,*)} \bar{D}_s^{*}$-type pentaquarks with double strangeness and the $Ω_{c}^{(*)}\bar D_s^{*}$-type pentaquarks with triple strangeness. The study explores various electromagnetic properties, including the magnetic moments, the transition magnetic moments, and the radiative decay behavior of these pentaquarks. To ensure realistic calculations, the $S$-$D$ wave mixing effect and the coupled channel effect are taken into account. By examining the electromagnetic properties of the hidden-charm molecular pentaquarks with double and triple strangeness, this research contributes to the deeper understanding of their spectroscopic behavior. These findings form a valuable addition to the ongoing investigation into the broader spectrum of properties exhibited by the hidden-charm molecular pentaquarks.
