论文摘要
在过去的几十年中，天文学和宇宙学数据集通过为存在暗物质，暗能量和非零中微子质量的有力证据提供了有力的证据，从而牢固确定了物理的存在。此外，原始扰动的产生很可能还取决于粒子物理学的标准模型之外的物理。理论工作包括导致新现象学预测的弦理论的早期宇宙的模型到有效的现场理论的发展，再到包括银河进化物理学的大规模宇宙学模拟，在分析和解释这些数据集以及提出新的途径以孤立这种新物理学的起源方面起着关键作用。在接下来的十年中，甚至更敏感的调查开始获取数据并正在计划。在这份白皮书中，我们描述了理论计划的关键领域，以优化这些新观察机会的物理投资回报率。
Over the past few decades, astronomical and cosmological data sets firmly established the existence of physics beyond the Standard Model of particle physics by providing strong evidence for the existence of dark matter, dark energy, and non-zero neutrino mass. In addition, the generation of primordial perturbations most likely also relies on physics beyond the Standard Model of particle physics. Theory work, ranging from models of the early universe in string theory that that led to novel phenomenological predictions to the development of effective field theories to large-scale cosmological simulations that include the physics of galaxy evolution, has played a key role in analyzing and interpreting these data sets and in suggesting novel paths forward to isolate the origins of this new physics. Over the next decade, even more sensitive surveys are beginning to take data and are being planned. In this white paper, we describe key areas of the theory program that will be needed to optimize the physics return on investment from these new observational opportunities.
