讲座摘要:In April 2019, the complete Belle II detector began its first physics run at the asymmetric energy e+e- SuperKEKB collider located in Tsukuba, Japan. The Belle II experiment aims at collecting an integrated luminosity of 50 ab-1, 50 times larger than its predecessor, Belle. The dataset collected in the running of 2019 corresponds to 10.57 fb-1, which not sufficient to probe new territory, but very useful for assessing the performance of the detector and rediscovering many known standard model processes. I will review the most significant physics results produced in the last few months, which include the observation of many particles and decay channels important for the Belle II physics program, and present an outlook for the short term prospects for the experiment.
