Kirill A. Bronnikov, Arkady A. Popov, Sergey G. Rubin

AI总结:

本文利用 f(R) 引力与非均匀额外维度,提出通过小参数形成和空间区域慢滚,从普朗克尺度恢复暴胀、电弱与宇宙学尺度以解决等级问题。

摘要:

我们讨论了解决等级问题的方法。我们表明,从普朗克尺度出发,暴胀、电弱和宇宙学这三个能量尺度可以得到恢复。文中提出了小参数的形成机制,从而成功解决该问题。该过程所涉及的工具是 f(R) 引力和非均匀额外维度。一个空间区域从普朗克尺度缓慢滚落到暴胀尺度会产生三个后果:无穷多因果上互不相连的区域(袖珍宇宙)经由成核过程形成;每个区域中的量子涨落产生多种不同的场以及额外维度度规分布;这些分布在足够低的能量尺度下稳定下来。

英文摘要:

We discuss the way of solving the hierarchy problem. We show that starting at the Planck scale, the three energy scales -- inflationary, electroweak and the cosmological ones can be restored. The formation of small parameters is proposed that leads to a successful solution of the problem. The tools involved in the process are $f(R)$ gravity and inhomogeneous extra dimensions. Slow rolling of a space domain from the Planck scale down to the inflationary one gives rise to three consequences: an infinite set of causally disconnected domains (pocket universes) are nucleated; quantum fluctuations in each domain produce a variety of different fields and an extra-dimensional metric distribution; these distributions are stabilized at a sufficiently low energy scale.
