LARGE体弦紧致化中的自然光隐光子

Naturally Light Hidden Photons in LARGE Volume String Compactifications

Mark Goodsell, Joerg Jaeckel, Javier Redondo, Andreas Ringwald

摘要:

额外的“隐藏的”U(1)规范因子是弦论的一个普遍特征,具有特殊的唯象意义。它们可以与标准模型的光子在动力学上混合,从而可以用于各种天体物理学和宇宙学的观测和实验室实验。本文研究了弦论大体积紧致化中隐U(1)的质量和动力学混合。我们发现,在这些情况下,隐藏的光子可以是自然光,它们与普通电磁光子的动力学混合可以是一个有趣的大小为不久的将来的实验和观测。

英文摘要:

Extra "hidden" U(1) gauge factors are a generic feature of string theory that is of particular phenomenological interest. They can kinetically mix with the Standard Model photon and are thereby accessible to a wide variety of astrophysical and cosmological observations and laboratory experiments. In this paper we investigate the masses and the kinetic mixing of hidden U(1)s in LARGE volume compactifications of string theory. We find that in these scenarios the hidden photons can be naturally light and that their kinetic mixing with the ordinary electromagnetic photon can be of a size interesting for near future experiments and observations.
