论文摘要

在这项研究中,我们讨论了$ p_ {cs}(4338)$和$ p_ {cs}(4459)$ hidden-hidden-charmed pentaquarks的磁矩,这与它们的子结构密切相关。这些状态的磁矩是借助QCD轻单元总规则方法来计算的,量子数$ i(j^p)= 0(1/2^ - )$和$ i(j^p)= 0(3/2^ - )$ for $ p_ {cs}(cs}(4338)$和$ P_ {CS}(cs}(cs}(44459),我们对磁矩的预测$μ_{p_ {p_ {cs}} = 0.34 \ pm 0.12〜μ_n $,用于$ p_ {cs}(4338)$ state,以及$μ__{p_ {p_ {cs}} = -1.67 \ pm pm 0.58〜μ_n $ for the $ p_ $ p_ $ p_ $ p_} $} {45。作为副产品,也已经获得了这些州的同音$ -1合作伙伴的磁矩。磁矩以$μ_{p_ {p_ {cs}} = 0.63 \ pm 0.21〜μ_n $和$μ__{p_ {p_ {cs}} = -3.33 \ pm 1.04〜μ_n $用于$ p_ {cs} $ p_ {cs} $ $ p_} $的isospin -1 parters国家分别。我们关于这些颜色单弦单线类型五夸克状态的磁矩的结果与文献的结果进行了比较。

In this study, we discuss the magnetic moment of $P_{cs}(4338)$ and $P_{cs}(4459)$ hidden-charmed pentaquarks, which are closely related to their substructures. The magnetic moments of these states are calculated with the help of the QCD light-cone sum rules method with quantum numbers $I(J^P) = 0(1/2^-)$ and $I(J^P) = 0(3/2^-)$ for $P_{cs}(4338)$ and $P_{cs}(4459)$, respectively. Our predictions for the magnetic moment $μ_{P_{cs}} = 0.34 \pm 0.12~μ_N$ for the $P_{cs}(4338)$ state, and $μ_{P_{cs}} = -1.67 \pm 0.58~μ_N $ for the $P_{cs}(4459)$ state. As a by-product, the magnetic moments of the isospin$-1$ partners of these states have also been obtained. The magnetic moments are obtained as $μ_{P_{cs}} = 0.63 \pm 0.21~μ_N$ and $μ_{P_{cs}} = -3.33 \pm 1.04 ~μ_N $ for the isospin-1 partners of the $P_{cs}(4338)$ and $P_{cs}(4459)$ states, respectively. Our results regarding the magnetic moments of these color singlet-singlet type pentaquark states are compared with the results in the literature.
