微扰步行动力学中的相变

Phase transitions in perturbative walking dynamics

Aleksandr Azatov, Miguel Vanvlasselaer

摘要:

在本文中,我们研究了一个玩具模型中的约束-解除约束相变的动力学,其中步行动力学是微扰实现的。我们研究的相变的性质,重点是它可以提供可能的宇宙学签名。有趣的是,只有当最轻的场--引力子/标量子的质量比其余的场轻得多,并且相变进行得很慢,导致随机引力波谱中的强信号时,模型才能很好地受到微扰控制。

英文摘要:

In this paper, we investigate the dynamics of the confinement-deconfinement phase transition in a toy model where the walking dynamics is realized perturbatively. We study the properties of the phase transition focusing on the possible cosmological signatures it can provide. Interestingly the model is well under perturbative control only when the mass of the lightest field - the dilaton/scalon is much lighter than the rest of the fields and the phase transition proceeds slowly leading to strong signals in the stochastic gravitational wave spectrum.
