重力调解中Q球形成的数值研究

Numerical study of Q-ball formation in gravity mediation

Takashi Hiramatsu, Masahiro Kawasaki, Fuminobu Takahashi

摘要:

我们研究Q球的形成在膨胀的宇宙在1D,2D和3D晶格模拟。我们获得了详细的Q球电荷分布,并发现该分布在Q^{3D}_{peak} \simeq 1.9 \times 10^{-2}处达到峰值(|Φ_{in}|/m)^2,比现有结果大约60%。基于数值模拟,我们讨论了Q球的形成过程。并对电荷分布可能偏离以往实验结果的问题作了评述。

英文摘要:

We study Q-ball formation in the expanding universe on 1D, 2D and 3D lattice simulations. We obtain detailed Q-ball charge distributions, and find that the distribution is peaked at Q^{3D}_{peak} \simeq 1.9\times 10^{-2} (|Φ_{in}|/m)^2, which is greater than the existing result by about 60%. Based on the numerical simulations, we discuss how the Q-ball formation proceeds. Also we make a comment on possible deviation of the charge distributions from what was conjectured in the past.
