论文摘要
LHC碰撞中可能发生了非标准模式均等。但是，任何此类违规行为都不会看到，但是由于目前尚未进行搜索。寻找违反平价的一个障碍是缺乏对所有形式敏感的模型无关的方法。我们通过展示一种在LHC上寻找奇偶校验物理学的有效且独立的方式来消除此障碍。该方法是数据驱动的，没有引用任何特定的平价侵略模型。取而代之的是，它检查数据以构建敏感的Parity-ODD事件变量（使用机器学习工具），并使用这些变量来测试独立数据中的奇偶校验不对称性。我们通过对从标准模型模拟和非标准平价模型进行模拟的数据进行测试来证明该方法的疗效。该结果使可能在粒子物理学中研究各种以前未开发的均等违规形式。数据和软件在https://zenodo.org/record/6827724上共享
Non-Standard-Model parity violation may be occurring in LHC collisions. Any such violation would go unseen, however, as searches are for it are not currently performed. One barrier to searches for parity violation is the lack of model-independent methods sensitive to all of its forms. We remove this barrier by demonstrating an effective and model-independent way to search for parity-violating physics at the LHC. The method is data-driven and makes no reference to any particular parity-violating model. Instead, it inspects data to construct sensitive parity-odd event variables (using machine learning tools), and uses these variables to test for parity asymmetry in independent data. We demonstrate the efficacy of this method by testing it on data simulated from the Standard Model and from a non-standard parity-violating model. This result enables the possibility of investigating a variety of previously unexplored forms of parity violation in particle physics.
