论文摘要
这是一个项目的简短摘要,该项目构建了标准模型时期的第一原理宇宙学,这是从电动过渡前不久开始的。宇宙学是从SM和一般相对性中的简单初始状态得出的。初始状态是半古典状态 - 集中在SM运动方程的经典解决方案附近 - 精确地由一些简单的条件指定。暗物质是经典的效果,是su(2) - 湿量表和希格斯田地的连贯状态。领先的顺序,古典宇宙仅包含暗物质。普通物质是由于经典轨迹周围SM场的波动而导致的校正。初始状态产生同质的,各向同性的,平坦的宇宙。没有可调节的参数。 SM以外的物理学没有被调用。到目前为止,仅进行了经典计算。波动的时间演变仍有待计算。
This is a short summary of a project to construct a first principles cosmology of the Standard Model epoch, the period starting shortly before the electro-weak transition. The cosmology is derived from a simple initial state entirely within the SM and General Relativity. The initial state is semi-classical -- concentrated near a classical solution of the SM equations of motion -- and is precisely specified by a few simple conditions. The dark matter is a classical effect, a coherent state of the SU(2)-weak gauge field and the Higgs field. The leading order, classical universe contains only the dark matter. Ordinary matter is a correction due to the fluctuations of the SM fields around the classical trajectory. The initial state produces a homogeneous, isotropic, flat universe. There are no adjustable parameters. No physics beyond the SM is invoked. Only the classical calculations have been done so far. The time evolution of the fluctuations remains to be calculated.
