Precision Flavour and Standard Model Physics Measurements at the Large Hadron Collider

在标准模型的已知部分进行精确测量，可以查明其预测的差异，从而产生新的物理现象的迹象。风味部门是最丰富的良好建模的精确领域之一，其中这些差异仍有待充分探索。由于大型强子对撞机提供的高亮度，ATLAS实验可以在一些测量中达到前所未有的精度，这些测量范围从粒子特性（产物离子机制，寿命等）的精确测定到新粒子特性的搜索和识别。苏塞克斯ATLAS小组目前正致力于寻找非常罕见的B介子分裂成两个介子的现象，以及测量Bs CP本征态的寿命。该学生将在苏塞克斯ATLAS小组分析活动中发挥主导作用，建立在风味部门现有分析的经验和对新物理的额外间接搜索的基础上。该学生还将参与与ATLAS事件选择系统（Trigger）操作、开发以及ATLAS升级的研发活动相关的硬件和软件项目。由于该项目以CERN为基础的活动处于中心地位，需要经常前往CERN和合作机构，包括在CERN的LTA期。

Precision measurements in known sectors of the Standard Model can pinpoint discrepancies with respect to its predictions, therefore producing indications of new physics phenomena. The Flavour sector is one of the richest well-modelled precision domains where these discrepancies are still to be fully explored. Thanks to the high luminosity provided by the LHC, the ATLAS experiment can achieve unprecedented precision in some of these measurements, which range from precision determinations of particle properties (product ion mechanisms, lifetimes etc.) to the search and identification of properties of new particles. The Sussex ATLAS group is currently involved in the search for the very rare disintegration of B mesons into two muons, as well as the measurement of the lifetime of Bs CP eigenstates. The student will take a leading role in one of the Sussex ATLAS group analysis activities, building on the experience of the existing analyses in the flavour sector and additional indirect searches for new physics. The student will also participate to hardware and software based projects related to ATLAS event selection system (Trigger) operation, development as well as R&D activities for the ATLAS upgrade. Due to the centrality of CERN-based activities in this project, frequent trips to CERN and collaborating institutes will be required, including a LTA period at CERN.
