多夸克系统中的湮灭相互作用与新强子态X(3872) 研究
Study on Annihilation Interaction in Multi-Quark Systems and the New Hadron State X(3872)

考虑多夸克系统内部正反夸克对湮灭为有效胶子，推导出了湮灭相互作用势；在不修改夸克模型参数的情况下，研究了ccuu系统的能谱，不仅合理地解释了新强子态X(3872)，而且还发现了J^PC=2⁺⁺的D^0*D^0*弱束缚态，并为BES和LHCb等国际实验合作组探测该粒子提出了建议.
Taking into account an effective one-gluon exchange between quark-antiquark, the authors deduced the annihilation interaction potential. The spectra of the ccuu system were calculated within a chiral constituent quark model with the same parameters as used in other works. In this work, the new hadron state X(3872) was convincingly explained, and a weak bound state D^0*D^0* with quantum number J^PC=2⁺⁺ was discovered. Some proposals are offered in this paper to such international organizations for experiment collaboration as BES and LHCb for the exploration of this particle
