Explosive Axion Production from Saxion

Yohei Ema, Kazunori Nakayama

摘要:

本文详细研究了超对称轴子模型中的轴子动力学及其对轴子产生的影响。我们发现,轴子的生产是非常有效的时,saxion振荡幅度远大于Peccei-Quinn标度,由于穗状行为的有效轴子质量。我们还考虑了axino生产和几个宇宙学的后果。讨论了从介子和轴子的非线性动力学中探测引力波的可能性。

英文摘要:

The dynamics of saxion in a supersymmetric axion model and its effect on the axion production is studied in detail. We find that the axion production is very efficient when the saxion oscillation amplitude is much larger than the Peccei-Quinn scale, due to a spike-like behavior of the effective axion mass. We also consider the axino production and several cosmological consequences. The possibility of detection of gravitational waves from the non-linear dynamics of the saxion and axion is discussed.
