标题： Beyond the Standard cosmological model with CMB

摘要： CMB各向异性测量以及最近的偏振测量在宇宙学中发挥了非常重要的作用。 除了精确确定“标准”宇宙学模型的各种参数外，观测还确立了一些构成宇宙学和宇宙结构形成模型基础的重要基本原理——平坦、统计各向同性的宇宙中的“非因果”关联、绝热原初扰动。 这些与膨胀范式的预期以及早期宇宙最简单实现的典型预测是一致的。 此外，引力不稳定是这些初始扰动形成结构的公认机制。 作为CMB各向异性和偏振观测到的原初扰动是最有说服力的证据，证明了早期宇宙中可能存在新的、可能是基本的物理现象。 目前，该领域正在超越“标准”模型的参数估计，寻找早期宇宙物理的微妙特征性标志。 显示英文摘要

摘要： Measurements of CMB anisotropy and, more recently, polarization have played a very important role in cosmology. Besides precise determination of various parameters of the `standard' cosmological model, observations have also established some important basic tenets that underlie models of cosmology and structure formation in the universe -- `acausally' correlated, adiabatic, primordial perturbations in a flat, statistically isotropic universe. These are consistent with the expectation of the paradigm of inflation and the generic prediction of the simplest realization of inflationary scenario in the early universe. Further, gravitational instability is the established mechanism for structure formation from these initial perturbations. Primordial perturbations observed as the CMB anisotropy and polarization is the most compelling evidence for new, possibly fundamental, physics in the early universe. The community is now looking beyond the parameter estimation of the `standard' model, for subtle, characteristic signatures of early universe physics.
