扭曲紧致化中隐藏的衰变暗物质

Decaying Hidden Dark Matter in Warped Compactification

Xingang Chen

摘要:

最近的PAMELA和ATIC/Fermi/HESS实验在高能宇宙射线中观测到过量的电子和正电子,但没有观测到反质子。为了解释这一结果,我们在弦论紧化中构建了一个衰减的隐藏暗物质模型,它包含了以下两个成分,扭曲紧化中的隐藏暗物质场景和衰减到标准模型的隐藏轻粒子的唯象建议。在这个模型中,在高维扭曲膜上,各种扭曲的Kaluza-Klein粒子和规范场的零模对标准模型起着隐藏的暗物质或介质的作用。

英文摘要:

The recent PAMELA and ATIC/Fermi/HESS experiments have observed an excess of electrons and positrons, but not anti-protons, in the high energy cosmic rays. To explain this result, we construct a decaying hidden dark matter model in string theory compactification that incorporates the following two ingredients, the hidden dark matter scenario in warped compactification and the phenomenological proposal of hidden light particles that decay to the Standard Model. In this model, on higher dimensional warped branes, various warped Kaluza-Klein particles and the zero-mode of gauge field play roles of the hidden dark matter or mediators to the Standard Model.
