Searches for lepton flavor violation in tau decays are unambiguous signatures of new physics. The branching ratios of tau leptons at the level of ${10}^{-10}$–${10}^{-9}$ can be probed using 50 $a{b}^{-1}$ of electron-positron annihilation data being collected by the Belle II experiment at the world’s highest luminosity accelerator, the SuperKEKB, located at the High Energy Accelerator Research Organization, KEK, in Tsukuba, Japan. Searches with such expected sensitivity will either discover new physics or strongly constrain several new physics models.

在 Belle II 的 Tau 衰变中搜索轻子风味违规

在 tau 衰变中寻找轻子风味破坏是新物理学的明确特征。tau 轻子的支化率${10}^{-10}$–${10}^{-9}$可以使用 50 进行探测$\mathrm{一个}{b}^{-1}$由位于日本筑波高能加速器研究组织 KEK 的世界上最高光度加速器 SuperKEKB 的 Belle II 实验收集的正负电子湮没数据。具有这种预期敏感性的搜索要么会发现新的物理学，要么会强烈限制几个新的物理学模型。
