Further study of $$c\bar{c}c\bar{c}$$ c c ¯ c c ¯ system within a chiral quark model
Abstract Inspired by the recent ATLAS and CMS experiments on the invariant mass spectrum of $$J/\psi J/\psi $$ J / ψ J / ψ , we systematically study the $$c\bar{c}c\bar{c}$$ c c ¯ c c ¯ system of $$J^{P}=0^{+}$$ J P = 0 + .

| description | Abstract Inspired by the recent ATLAS and CMS experiments on the invariant mass spectrum of $$J/\psi J/\psi $$ J / ψ J / ψ , we systematically study the $$c\bar{c}c\bar{c}$$ c c ¯ c c ¯ system of $$J^{P}=0^{+}$$ J P = 0 + . In the framework of chiral quark model, we have carried out bound-state calculation and resonance-state calculation respectively by using Real-scaling method. The results of bound-state calculation show that there are no bound states in the $$c\bar{c}c\bar{c}$$ c c ¯ c c ¯ with $$0^{+}$$ 0 + system. The resonance-state calculation shows that there are four possible resonances: R(6923), R(6996), R(7060) and R(7159). R(6923) and R(7159) are experimental candidates for X(6900) and X(7200), whose main decay channel is $$J/\psi J/\psi $$ J / ψ J / ψ . It is important to note that the another major decay channel of R(7159) is $$\chi _{c0} \chi _{c0}$$ χ c 0 χ c 0 , and the $$\chi _{c0} \chi _{c0}$$ χ c 0 χ c 0 is also the main decay channel of R(6996), R(7060). Therefore, we propose to search experimentally for these two predicted resonances in the $$\chi _{c0} \chi _{c0}$$ χ c 0 χ c 0 invariant mass spectrum. |
