暴胀宇宙学中的再加热:理论与应用

Reheating in Inflationary Cosmology: Theory and Applications

Rouzbeh Allahverdi, Robert Brandenberger, Francis-Yan Cyr-Racine, Anupam Mazumdar

摘要:

再加热是暴胀宇宙学的重要组成部分。它描述了标准物质粒子在加速膨胀阶段之后的产生。我们给出了一个回顾的再加热过程,重点是在预热阶段的深入讨论,其特征在于由于参数共振或快子不稳定性的指数粒子生产。我们给出了一个简短的概述预热后的热化过程,并结束了一些应用超对称理论和宇宙学中的其他问题,如重子生成,暗物质和度规预热的调查。

英文摘要:

Reheating is an important part of inflationary cosmology. It describes the production of Standard Matter particles after the phase of accelerated expansion. We give a review of the reheating process, focusing on an in-depth discussion of the preheating stage which is characterized by exponential particle production due to a parametric resonance or tachyonic instability. We give a brief overview of the thermalization process after preheating and end with a survey of some applications to supersymmetric theories and to other issues in cosmology such as baryogenesis, dark matter and metric preheating.
