Charmonium and bottomonium spectroscopy at Belle II

摘要:

在SuperKEKB能量不对称$e^+e^-$对撞机上进行的Belle II实验是对日本筑波KEK B工厂设施的升级。该实验于2019年开始运行,旨在记录比其前身多50倍的数据。Belle II是唯一能够研究所谓的“XYZ”粒子的人:由三个以上夸克组成的重奇异强子。首先发现的贝尔,这些现在的数字在几十个,并代表了一个新的类别出现在量子色动力学。我们目前从Belle II数据中获得的最新结果,以及探索奇异和常规夸克偶素物理的未来前景。

英文摘要:

The Belle II experiment at the SuperKEKB energy-asymmetric $e^+e^-$ collider is an upgrade of the B factory facility at KEK in Tsukuba, Japan. The experiment began operation in 2019 and aims to record a factor of 50 times more data than its predecessor. Belle II is uniquely capable of studying the so-called "XYZ" particles: heavy exotic hadrons consisting of more than three quarks. First discovered by Belle, these now number in the dozens, and represent the emergence of a new category within quantum chromodynamics. We present recent results obtained from Belle II data, and the future prospects to explore both exotic and conventional quarkonium physics.
