暴胀宇宙中的粒子产生和再加热

Particle production and reheating in the inflationary universe

Chris M Graham, Ian G Moss

摘要:

热场论适用于粒子生产率的暴胀模型,导致新的结果催化,或两个阶段的衰变,大规模的领域作为衰变通道的生产光场。膨胀宇宙中Bolztmann方程的数值研究表明,在小振幅暴胀子振荡或缓慢移动的暴胀子场旁边产生的粒子分布可以热化。

英文摘要:

Thermal field theory is applied to particle production rates in inflationary models, leading to new results for catalysed, or two-stage decay, where massive fields act as decay channels for the production of light fields. A numerical investigation of the Bolztmann equation in an expanding universe shows that the particle distributions produced during small amplitude inflaton oscillations or alongside slowly moving inflaton fields can thermalise.
