粒子III的Lorentz和置换不变量:限制宇称破坏的非标准源

Lorentz and permutation invariants of particles III: constraining non-standard sources of parity violation

Christopher G. Lester, Ward Haddadin, Ben Gripaios

摘要:

比较粒子物理实验数据中宇称奇事件变量分布的正半部分和负半部分,可以提供对非标准宇称违反来源的敏感性。这种技术得益于缺乏对模拟或理论模型的一阶依赖性,但迄今为止缺乏枚举所有可识别信号的系统手段。为了解决这个问题,本文试图构建奇偶奇事件变量集,这些事件变量集可以被证明能够揭示任何洛伦兹不变的非标准奇偶破坏源的存在,这些非标准奇偶破坏源可以在由表现出某些置换对称性的真实非类空四动量组组成的数据中可见。

英文摘要:

Comparisons of the positive and negative halves of the distributions of parity-odd event variables in particle-physics experimental data can provide sensitivity to sources of non-standard parity violation. Such techniques benefit from lacking first-order dependence on simulations or theoretical models, but have hitherto lacked systematic means of enumerating all discoverable signals. To address that issue this paper seeks to construct sets of parity-odd event variables which may be proved to be able to reveal the existence of any Lorentz-invariant source of non-standard parity violation which could be visible in data consisting of groups of real non space-like four-momenta exhibiting certain permutation symmetries.
