额外自然翘曲暴胀

Extranatural Warped Inflation

Toshiki Kawai, Yoshiharu Kawamura

AI总结:

研究在 Randall-Sundrum 翘曲时空中,五维 ${\ m U(1)}$ 规范场的额外分量能否诱导早期宇宙暴胀,发现量子修正有效势可作为暴胀子势且符合 Planck 2018 结果。

摘要:

我们研究早期宇宙中的暴胀能否由 Randall-Sundrum 翘曲时空中五维 ${\ m U(1)}$ 规范场的额外分量诱导。通过寻找与 Planck 2018 结果一致的参数区域,我们证明由量子修正获得的有效势能可作为暴胀子势。在我们的模型中,参与暴胀的场遵循与可见粒子不同类型的边界条件,且残存的 Wilson line 相可对标准模型之外的物理发挥特定作用。

英文摘要:

We investigate whether inflation in the early universe can be induced by an extra component of a five-dimensional ${\rm U(1)}$ gauge field in the Randall-Sundrum warped spacetime or not. We show that an effective potential obtained by quantum corrections can act as an inflaton potential by finding parameter regions consistent with Planck 2018 results. In our model, fields involved in inflation obey a different type of boundary condition from that of the visible particles, and a surviving Wilson line phase can play a specific role for physics beyond the standard model.
