Abstract

Between the years 2015 and 2019, members of the Horizon 2020-funded Innovative Training Network named “AMVA4NewPhysics” studied the customization and application of advanced multivariate analysis methods and statistical learning tools to high-energy physics problems, as well as developed entirely new ones. Many of those methods were successfully used to improve the sensitivity of data analyses performed by the ATLAS and CMS experiments at the CERN Large Hadron Collider; several others, still in the testing phase, promise to further improve the precision of measurements of fundamental physics parameters and the reach of searches for new phenomena. In this paper, the most relevant new tools, among those studied and developed, are presented along with the evaluation of their performances.

大型强子对撞机新物理搜索多变量分析方法的进展

在2015年至2019年期间，地平线2020资助的创新培训网络“AMVA4NewPhysics”的成员研究了先进的多元分析方法和统计学习工具在高能物理问题上的定制和应用，并开发了全新的问题。其中许多方法被成功地用于提高欧洲核子研究中心大型强子对撞机上ATLAS和CMS实验数据分析的灵敏度;其他几个仍处于测试阶段的项目，有望进一步提高基本物理参数测量的精度，并扩大对新现象的搜索范围。在本文中，介绍了研究和开发的最相关的新工具，并对其性能进行了评价。

期刊介绍： Reviews in Physics is a gold open access Journal, publishing review papers on topics in all areas of (applied) physics. The journal provides a platform for researchers who wish to summarize a field of physics research and share this work as widely as possible. The published papers provide an overview of the main developments on a particular topic, with an emphasis on recent developments, and sketch an outlook on future developments. The journal focuses on short review papers (max 15 pages) and these are freely available after publication. All submitted manuscripts are fully peer-reviewed and after acceptance a publication fee is charged to cover all editorial, production, and archiving costs.
