The project covers searches for new heavy gauge bosons via lepton pairs inthe final state. This is considered as a 'golden' channel for discoveries due tothe clean signature at low background rates. The anticipated increase in thestatistics with the new LHC Run 3 will allow extending the search rangefurther. The student will study the fully available statistics and develop newmachine learning-based analysis tools going thus beyond the traditional cutbased analysis pursued so far. Particular emphasis will be given to theinterpretation of the Drell-Yan data at the highest masses which can be siftedalso for new contact interaction types. The student will develop a novelmethod of interpreting jointly electron-proton data from the HERA colliderand Drell-Yan data from ATLAS to gain world best limits on our knowledge ofan effective quark radius.Beyond the necessary training in the world of big ATLAS data using gridcomputing resources and advanced, state-of-the art computer-based analysistools, the student will get practical training with muon system operation atCERN led by MPI staff. The student will contribute to the new Run 3 datataking as well as contributions to the analysis of simulated data. Thus, thestudent will get training that may lead to a variety of career paths rangingfrom a data scientist in industry or to further academic career.The main expected outcome of the project would be a discovery of a newheavy gauge boson. If this is not the case, then the planned new analysistechniques are expected to be used for new kind of limits of contactinteractions and the world's best effective quark radius in particular.DH/Feb2019The project would open up a new link to the MPI Munich which belongs toone of the strongest institutions in Germany

该项目包括通过最终状态下的轻子对寻找新的重规范玻色子。这被认为是一个'黄金'渠道的发现，由于清洁的签名在低背景率。新的LHC运行3的统计数据的预期增加将允许进一步扩展搜索范围。学生将研究完全可用的统计数据，并开发新的基于机器学习的分析工具，从而超越迄今为止所追求的传统基于切割的分析。特别强调的是将给予theinterpretation的Drell-Yan数据在最高的质量，也可以筛选新的接触相互作用类型。学生将开发一种新的方法来解释来自HERA对撞机的电子质子数据和来自ATLAS的Drell-Yan数据，以获得我们对有效夸克半径的知识的世界最佳极限。除了使用网格计算资源和先进的基于计算机的分析工具的ATLAS大数据世界的必要培训外，学生将在MPI工作人员的带领下在CERN获得μ子系统操作的实践培训。学生将为新的运行3数据标记以及模拟数据的分析做出贡献。因此，学生将接受培训，可能会导致各种职业道路，从工业数据科学家到进一步的学术生涯。该项目的主要预期成果将是发现一种新的规范玻色子。如果不是这样的话，那么计划中的新分析技术预计将用于接触相互作用的新限制，特别是世界上最好的有效夸克半径。DH/Feb 2019该项目将开辟一个新的链接到MPI慕尼黑，属于德国最强大的机构之一
