AI总结:

本文扩展 ALPiNIST 蒙特卡洛框架以支持重中性轻子等弱相互作用粒子,并强调统一模拟输入对实验参数灵敏度评估的关键作用。

摘要:

弱相互作用粒子是粒子物理学标准模型的一种常被考虑的扩展。在许多理论框架中,这些粒子能够解释与当前模型存在张力的观测物理现象。ALPiNIST 是一个简化的蒙特卡洛框架,旨在评估过去、现在和未来的短基线与长基线实验对不同类轴子粒子模型的灵敏度。我们介绍了该框架的扩展,以容纳新类别的弱相互作用粒子,重点是重中性轻子。这一扩展具有特别充分的动机,因为它同时解决了标准模型中多个悬而未决的问题。文中强调了输入对所得参数灵敏度的根本重要性,以及因此对统一模拟设置的需求。

英文摘要:

Feebly Interacting Particles are a commonly considered extension to the Standard Model of Particle Physics. In many theoretical frameworks these particles can explain observed physical phenomena which are in tension with the current model. \textsc{ALPiNIST} is a simplified Monte Carlo framework aimed at evaluating past, present, and future, short and long baseline experiments for their sensitivities to different models of Axion-Like Particles. We present the extension of this framework to accommodate new classes of Feebly Interacting Particles with emphasis on Heavy Neutral Leptons. This extension is especially well motivated, solving multiple of the standing issues with the Standard Model at the same time. The fundamental importance of inputs on the resulting parameter sensitivity, and thus the need for a unified simulation set-up, is highlighted.
