【摘要】 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.更多还原

【Abstract】 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.更多还原
