暴胀期间产生发光物质和暗物质

Generating Luminous and Dark Matter During Inflation

Neil D. Barrie, Archil Kobakhidze

摘要:

我们提出了一种新的机制,在宇宙暴胀过程中产生发光物质和暗物质。根据这一机制,普通物质和暗物质携带共同的电荷,这与异常的$ U(1)_{X} $基团有关。反常项源$ \mathcal{CP} $和$ U(1)_{X} $在暴胀过程中的电荷违反过程,产生相应的非零陈-西蒙斯数,随后再处理成重子和暗物质密度。开发的一般框架,然后应用到两个可能的扩展标准模型与异常规范$B$和$B-L$,每个额外的暗物质的候选人。

英文摘要:

We propose a new mechanism for generating both luminous and dark matter during cosmic inflation. According to this mechanism, ordinary and dark matter carry common charge which is associated with an anomalous $ U(1)_{X} $ group. Anomaly terms source $ \mathcal{CP} $ and $ U(1)_{X} $ charge violating processes during inflation, producing corresponding non-zero Chern-Simons numbers which are subsequently reprocessed into baryon and dark matter densities. The general framework developed is then applied to two possible extensions of the Standard Model with anomalous gauged $B$ and $B-L$, each with an additional dark matter candidate.
