希格斯粒子（Higgs）的发现填补了标准模型（SM）中最后一个神秘粒子的空白，它赋予所有其他粒子以质量，然而种种迹象表明这个模型还是不完备的，在它之外应该有新物理的存在。为了证明我们发现的就是标准模型的Higgs，与Higgs汤川耦合相关的Higgs到双陶子衰变的信号测量就显得极为重要。申请人拟展开基于大型强子对撞机（LHC）新取数阶段（Run-2和Run-3）数据的双陶子传统物理分析，以及在ATLAS实验上寻找与陶子有关的新物理工作。课题研究的一部分时间在欧洲核子中心（CERN）进行，一部分时间在依托单位进行。

The discovery of Higgs has cleared the last mysterious piece of the Standard Model (SM). It gives mass to all the other fundamental particles that we observe. However, there are hints that the SM is not complete, and there should be New Physics beyond SM. To prove that what we have found is indeed a SM Higgs, the decay of Higgs to two tau particles, which is related to the Higgs Yukawa coupling, becomes very important. The applicant plans to carry out the traditional di-tau physics analysis with the LHC Run2 data, and the search for New Physics with the ATLAS experiment that involve taus. The research time will be partially spent at CERN, and partially at the home institute.
