由已建立的$P_c$分子态激发的具有开奇异态的隐魅五夸克态的质量行为

Mass behavior of hidden-charm pentaquarks with open-strange inspired by these established $P_c$ molecular states

Rui Chen, Xiang Liu

摘要:

在对$P_c$态($P_c(4312)/P_c(4440)/P_c(4457)$)的介子-重子分子解释的激励下,利用耦合道分析方法,系统地研究了$S-$波魅-奇异重子$Ξ_c^{(\prime,*)}$与反粲介子$\bar{D}^{(*)}$之间的相互作用.利用$SU(3)$味对称性和重夸克对称性,将单玻色子交换模型中$Ξ_c^{(\prime,*)}\bar{D}^{(*)}$相互作用的有效势与$Σ_c^{(*)}\bar{D}^{(*)}$系统中的有效势联系起来.我们的结果可以预言几种具有奇异性$|S|=1$的隐魅分子五夸克态,包括具有$I(J^P)=0,1(1/2^-)$的$Ξ_c^{\prime}\bar{D}$态,具有$0,1(3/2^-)$的$Ξ_c^*\bar{D}$态,具有$0(1/2^-)$和$0,1(3/2^-)$的$Ξ_c^{\prime}\bar{D}^*$态,以及具有$0(1/2^-,3/2^-,5/2^-)$的$Ξ_c^*\bar{D}^*$态.

英文摘要:

Stimulated by the meson-baryon molecular interpretations of the $P_c$ states ($P_c(4312)/P_c(4440)/P_c(4457)$), we systematically study the interactions between an $S-$wave charm-strange baryon $Ξ_c^{(\prime,*)}$ and an anti-charmed meson $\bar{D}^{(*)}$ in a coupled channel analysis. Effective potentials for the $Ξ_c^{(\prime,*)}\bar{D}^{(*)}$ interactions in a one-boson-exchange model can be related to those in the $Σ_c^{(*)}\bar{D}^{(*)}$ systems by using the $SU(3)$ flavor symmetry and heavy quark symmetry. Our results can predict several promising hidden-charm molecular pentaquarks with strangeness $|S|=1$, which include the $Ξ_c^{\prime}\bar{D}$ states with $I(J^P)=0,1(1/2^-)$, the $Ξ_c^*\bar{D}$ states with $0,1(3/2^-)$, the $Ξ_c^{\prime}\bar{D}^*$ states with $0(1/2^-)$ and $0,1(3/2^-)$, and the $Ξ_c^*\bar{D}^*$ states with $0(1/2^-,3/2^-,5/2^-)$.
