摘要

2012年发现希格斯玻色子后，欧洲核子研究中心（CERN）大型强子对撞机（Large Hadron Collider）的ATLAS实验加强了对超对称的探索。从2015年至2018年收集的碰撞数据中增加的综合亮度和更高的质心能量，以及通过使用新的实验特征和创新的分析技术，对未探索的超对称参数空间区域获得新的灵敏度，搜索计划在广度和深度上都有所扩展。本报告总结了在ATLAS上使用高达140 fb−1的s=13TeV的pp碰撞进行的超对称搜索，包括在有或没有r宇称守恒的情况下对胶子、夸克和电弱子产生的限制，以及一些超对称粒子长寿命的模型。

The quest to discover supersymmetry at the ATLAS experiment

The search for supersymmetry with the ATLAS experiment at the CERN Large Hadron Collider intensified after the discovery of the Higgs boson in 2012. The search programme expanded in both breadth and depth, profiting from the increased integrated luminosity and higher centre-of-mass energy for the collision data collected between 2015 and 2018, and gaining new sensitivity to unexplored areas of supersymmetry parameter space through the use of novel experimental signatures and innovative analysis techniques. This report summarises the supersymmetry searches at ATLAS using up to 140 fb⁻¹ of

, including the limits set on the production of gluinos, squarks, and electroweakinos for scenarios with or without R-parity conservation, and including models where some of the supersymmetric particles are long-lived.

期刊介绍： Physics Reports keeps the active physicist up-to-date on developments in a wide range of topics by publishing timely reviews which are more extensive than just literature surveys but normally less than a full monograph. Each report deals with one specific subject and is generally published in a separate volume. These reviews are specialist in nature but contain enough introductory material to make the main points intelligible to a non-specialist. The reader will not only be able to distinguish important developments and trends in physics but will also find a sufficient number of references to the original literature.
