摘要

标准模型所预测的轻子味普适性受到了涉及tau和带电轻子的介子衰变的各种测量的挑战。Belle II实验于2018年春季开始记录第一次碰撞数据,并提供了一个独特的实验室,可以高精度地研究轻子和半轻子衰变中的轻子风味普遍性。在这里,我们报告了利用现有的Belle II数据建立(半)陶子衰变的首次测量和→gag通道的初步结果的现状,并讨论了研究((∗))异常的未来潜力。

Leptonic and semileptonic decays with taus at the Belle II experiment
Lepton flavour universality as predicted by the Standard Model is challenged by various measurements of meson decays involving tau and charged light leptons. The Belle II experiment started recording first collision data in spring 2018 and offers a unique laboratory to study lepton flavour universality in leptonic and semileptonic decays at high precision. Here we report the status of establishing first measurements of (semi) tauonic decays and preliminary results of the → gag channel using the available Belle II data, and discuss the future potential of investigating '( (∗) ) anomalies.
