论文摘要
包含$ c \ bar c $ plus $ s \ bar s $（或在群众区域$（3900-4700）$ MEV中的$ s \ b s $（或轻$ q \ bar q $）夸克的共振，在相对论强的耦合理论中进行了分析，有或没有通道耦合现象。提出了传统的炭谱，该光谱是用相对论的弦弦汉顿式计算的，该谱系不含拟合参数，而对于高激发，使用了通用扁平的限制电势。结果表明，可以将$ x（4274），x（4500），x（4700）$识别为$ 3 \，^3p_1，4 \，^3p_0，5 \，^3p_0 $状态。当两个介子$ m_1，m_2 $转移到另外两个介子$ m_3，m_4 $ and back（无限次数）时，使用耦合通道（重新耦合）理论考虑异国情调状态，创建四夸克系统。共鸣$ x（3875），x（3915），z_ {cs}（3985），x（4140）$可以用这种方式解释为$ s $ - 波型衰减频道中的异国情调的四夸克州。
The resonances, containing $c\bar c$ plus $s\bar s$ (or light $q\bar q$) quarks in the mass region $(3900-4700)$ MeV, are analyzed in the relativistic strong coupling theory, with and without channel coupling phenomena. The conventional charmonium spectrum is presented, being calculated with the relativistic string Hamiltonian, which does not contain fitting parameters, while for high excitations the universal flattened confining potential is used. It is shown that $X(4274),X(4500),X(4700)$ can be identified as $3\,^3P_1, 4\,^3P_0, 5\,^3P_0$ states. The exotic states are considered using the coupled-channel (recoupling) theory, when two mesons $m_1,m_2$ transfer into another two mesons $m_3, m_4$ and back (infinite number of times), creating the four-quark systems. The resonances $X(3875), X(3915), Z_{cs}(3985), X(4140)$ can be explained in this way as the exotic four-quark states in the $S$-wave decay channels.
