One of the most effective routes for studying the Standard Model electroweak sector is via decays of involving the production Higgs boson or two bosons that in turn decay into leptons. The project aims to:- Contribute to the search for Higgs decays to two muons. This effort is tightly coupled to the performance improvements of lepton reconstruction and identification.- Observe the Higgs decay to two muons and measure the relevant Yukawa coupling constants. The LHC is expected to deliver ~ 150 fb-1 during RUN III with a centre of mass energy of 13.6 TeV over the next 3 years and this measurement is one of the most anticipated results expected from the ATLAS collaboration in the next few years. - The increased centre of mass energy will also open the window for measuring di-boson production cross sections in a higher energy than ever achieved before.Lucy will qualify as ATLAS author and perform service work related to the ATLAS experiment operation. To this effect she is expected to contribute to the ATLAS electron performance group. The aim will be to prepare aspects of the ATLAS electron and photon reconstruction in view of the installation of the updated ATLAS ITK tracker.

研究标准模型电弱区的最有效途径之一是通过涉及产生希格斯玻色子或两个玻色子的衰变，然后这两个玻色子又衰变成轻子。该项目的目标是：- 为寻找希格斯衰变为两个μ子做出贡献。这项工作与轻子重建和识别的性能改进紧密结合。 - 观察希格斯衰变为两个μ子并测量相关的汤川耦合常数。 LHC 预计在未来 3 年内在 RUN III 期间提供约 150 fb-1，质心能量为 13.6 TeV，这一测量是未来几年 ATLAS 合作最令人期待的结果之一。 - 质心能量的增加也将为测量比以往更高的能量的双玻色子产生截面打开了窗口。露西将有资格成为 ATLAS 作者并执行与 ATLAS 实验操作相关的服务工作。为此，她预计将为 ATLAS 电子性能小组做出贡献。目的是鉴于安装更新的 ATLAS ITK 跟踪器，为 ATLAS 电子和光子重建做好准备。
