标题： EuCAPT White Paper: Opportunities and Challenges for Theoretical Astroparticle Physics in the Next Decade

摘要： 天体粒子物理学正在经历一场深刻的变革，这得益于一系列非凡的新成果，例如通过冰立方探测器发现高能宇宙中微子、通过 LIGO 和 Virgo 探测到引力波，以及其他许多成果。 本文档是由欧洲天体粒子理论联盟（EuCAPT）协调，数百位理论天体粒子物理学家和宇宙学家共同合作的成果。 本文面向整个天体粒子物理学界，探讨了我们研究领域的未来理论机遇与挑战，尤其强调了不同子领域之间的潜在协同作用，以及利用多信使观测解决最根本的开放问题的前景。 显示英文摘要

摘要： Astroparticle physics is undergoing a profound transformation, due to a series of extraordinary new results, such as the discovery of high-energy cosmic neutrinos with IceCube, the direct detection of gravitational waves with LIGO and Virgo, and many others. This white paper is the result of a collaborative effort that involved hundreds of theoretical astroparticle physicists and cosmologists, under the coordination of the European Consortium for Astroparticle Theory (EuCAPT). Addressed to the whole astroparticle physics community, it explores upcoming theoretical opportunities and challenges for our field of research, with particular emphasis on the possible synergies among different subfields, and the prospects for solving the most fundamental open questions with multi-messenger observations.
