论文摘要
我们在两个夸克模型的框架中对带有夸克内容的五夸克系统进行了动态计算：手性夸克模型（CHQM）和Quark Delocalization Color Secraling Modeling模型（QDCSM）。给出了Baryon和Meson簇之间的有效潜力，还研究了可能的结合状态。此外，还进行了对开放通道的散射过程的研究，以寻找任何共振状态。结果表明，$ω（2012）$不适用于当前夸克模型中的$ξ^{*} \ bar {k} $分子状态的解释。两个共振指出：$ ij^{k}^{*} $ with $ ij^{p} = 0 \ frac {3} {2} {2}^{ - } $（$ m = 2328 \ sim2374 $ mev，$ c = 57 = 57 \ sim65.5 $ mev）和$ ij^{p} = 1 \ frac {3} {2}^{ - } $（$ m = 2341 \ sim2386 $ MEV，$γ= 31.5 \ sim100 $ MEV）在QDCSM和CHQM中都获得了这两个状态的QDCSM和CHQM，这两个状态都有更多的搜索，并且在搜索中都有搜索，并且有价值均被搜索。
We conduct a dynamical calculation of pentaquark systems with quark contents $sssu\bar{u}$ in the framework of two quark models: the chiral quark model(ChQM) and quark delocalization color screening model(QDCSM). The effective potentials between baryon and meson clusters are given, and the possible bound states are also investigated. Besides, the study of the scattering process of the open channels is also performed to look for any resonance state. The results show that the $Ω(2012)$ is not suitable for the interpretation as a $Ξ^{*} \bar{K}$ molecular state in present quark models. Two resonance states: the $Ξ^{*}\bar{K}^{*}$ with $IJ^{P}=0\frac{3}{2}^{-}$ ($M=2328\sim2374$ MeV, $Γ=57\sim65.5$ MeV) and $IJ^{P}=1\frac{3}{2}^{-}$ ($M=2341\sim2386$ MeV, $Γ=31.5\sim100$ MeV) are obtained in both QDCSM and ChQM, which indicates that both of these two states are more possible to be existed and worthy of being searched by future experiments.
