摘要

高能宇宙射线在地球大气中相互作用并产生广泛的空气阵雨(EASs),这可以用地面上的大型探测器阵列进行测量。这些测量的解释依赖于EAS开发的模型,这代表了在极端条件下测试量子色动力学(QCD)的挑战和机会。在QCD的非微扰状态下,低动量转移下的强子-离子碰撞驱动了EAS的发展。在这些条件下,强子的产生不能用第一性原理来描述,这些相互作用不能用现有的对撞机实验来探测。因此,EAS发展的精确测量提供了强子相互作用中多粒子产生的独特探针。

Probing Hadronic Interactions with Cosmic Rays
High-energy cosmic rays interact in the Earth’s atmosphere and produce extensive air showers (EASs) which can be measured with large detector arrays at the ground. The interpretation of these measurements relies on models of the EAS development which represents a challenge as well as an opportunity to test quantum chromodynamics (QCD) under extreme conditions. The EAS development is driven by hadron-ion collisions under low momentum transfer in the non-perturbative regime of QCD. Under these conditions, hadron production cannot be described using first principles and these interactions cannot be probed with existing collider experiments. Thus, accurate measurements of the EAS development provide a unique probe of multi-particle production in hadronic interactions.
