标题： Nature of X(3872) from data

摘要： 该类底夸克态X(3872)的性质被研究，并基于现有的实验数据讨论了其本质。 特别是，我们分析了Belle和BaBar合作组的新数据，并认为，虽然BaBar的数据更倾向于在D\bar{D}*系统中的动态生成的虚态，但新的Belle数据明确表明在X波函数中存在显著的c\bar{c} 2^3P_1成分。 显示英文摘要

摘要： Properties of the charmonium-like state X(3872) are investigated and its nature is discussed as based on the existing experimental data. In particular, we analyse the new data from Belle and BaBar Collaborations and argue that, while the BaBar data prefer the dynamically generated virtual state in the D\bar{D}* system, the new Belle data clearly indicate a sizable c\bar{c} 2^3P_1 component in the X wave function.
