%X 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&lt;i&gt;J&lt;/i&gt;&lt;sup&gt;&lt;i&gt;PC&lt;/i&gt;&lt;/sup&gt;=2&lt;sup&gt;++&lt;/sup&gt;的&lt;i&gt;D&lt;/i&gt;&lt;sup&gt;0*&lt;/sup&gt;&lt;span style='text-decoration:overline'&gt;&lt;i&gt;D&lt;/i&gt;&lt;/span&gt;&lt;sup&gt;0*&lt;/sup&gt;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.&lt;br&gt;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 &lt;i&gt;D&lt;/i&gt;&lt;sup&gt;0*&lt;/sup&gt;&lt;span style='text-decoration:overline'&gt;&lt;i&gt;D&lt;/i&gt;&lt;/span&gt;&lt;sup&gt;0*&lt;/sup&gt; with quantum number &lt;i&gt;J&lt;/i&gt;&lt;sup&gt;&lt;i&gt;PC&lt;/i&gt;&lt;/sup&gt;=2&lt;sup&gt;++&lt;/sup&gt; 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
