Title: 最高能量粒子物理与皮埃尔·奥格天文台

Abstract: Astroparticles offer a new path for research in the field of particle physics, allowing investigations at energies above those accesible with accelerators. Ultra-high energy cosmic rays can be studied via the observation of the showers they generate in the atmosphere. The Pierre Auger Observatory is a hybrid detector for ultra-high energy cosmic rays, combining two complementary measurement techniques used by previous experiments, to get the best possible measurements of these air showers. Shower observations enable one to not only estimate the energy, direction and most probable mass of the primary cosmic particles but also to obtain some information about the properties of their hadronic interactions. Results that are most relevant in the context of determining hadronic interaction characteristics at ultra-high energies will be presented. Show Chinese abstract

Abstract: 天体粒子为粒子物理领域研究提供了新的途径，使在加速器可达到的能量以上的能量范围进行研究成为可能。 超高能宇宙射线可以通过观察它们在大气中产生的级联来研究。 皮埃尔·奥格观测站是一种混合探测器，用于超高能宇宙射线，结合了以前实验使用的两种互补测量技术，以获得这些空气级联的最佳测量结果。 级联观测不仅能够估计原始宇宙粒子的能量、方向和最可能的质量，还可以获得有关其强子相互作用特性的某些信息。 将介绍在确定超高能下强子相互作用特性方面最相关的结果。
