论文摘要
X（3872）是有史以来最令人困惑的共振之一。 Belle合作于2003年首次出现，它索取了一百位实验物理学家和数十名理论家的努力，如今，他们尚未阐明这种特殊的共鸣状态的本质。它在几种衰减模式和不同的生产机制中都可以看到，并通过几个实验证实，因此已建立了良好的确认，并且最近被称为$χ_{C1}（3872）$。在这里，我们报告了X（3872）与早期Belle II数据的重新发现，并讨论一旦Belle II实现了完整的整合计划的亮度，将来进行了未来测量的计划。
The X(3872) is one of the most puzzling resonances ever observed. First seen by the Belle Collaboration in 2003, it solicited the effort of a hundred of experimental physicists and dozens of theorists, who nowadays are trying yet to shed light on the nature of this peculiar resonant state. It was seen in several decay modes and different production mechanisms, and confirmed by several experiments, so it is well established, and recently is addressed as the $χ_{c1} (3872)$. Here we report about a re-discovery of the X(3872) with early Belle II data, and discuss plans for future measurements once the full integrated planned luminosity will be achieved by Belle II.
