标题： Cosmic Physics: The High Energy Frontier

摘要： 宇宙射线已被观测到的能量比最佳粒子加速器的能量大$10^8$倍。 对天体物理粒子（强子、中微子和光子）在其最高观测能量下的研究，对基础物理和天体物理都有意义。 因此，宇宙高能前沿是新粒子物理的交汇点。 本综述讨论了在最高观测能量下宇宙射线和宇宙伽马射线的物理和天体物理领域的最新进展，以及极高能宇宙中微子的相关物理和天体物理问题。 这些主题涉及大统一理论、洛伦兹不变性破坏，以及普朗克尺度物理和量子引力等问题。 显示英文摘要

摘要： Cosmic rays have been observed up to energies $10^8$ times larger than those of the best particle accelerators. Studies of astrophysical particles (hadrons, neutrinos and photons) at their highest observed energies have implications for fundamental physics as well as astrophysics. Thus, the cosmic high energy frontier is the nexus to new particle physics. This overview discusses recent advances being made in the physics and astrophysics of cosmic rays and cosmic gamma-rays at the highest observed energies as well as the related physics and astrophysics of very high energy cosmic neutrinos. These topics touch on questions of grand unification, violation of Lorentz invariance, as well as Planck scale physics and quantum gravity.
