5D扭曲背景中的自然膨胀

Natural inflation in 5D warped backgrounds

R. Gonzalez Felipe, N. M. C. Santos

摘要:

根据Wilkinson微波各向异性探测器(WMAP)五年的观测数据,讨论了基于五维规范理论预言的赝Nambu-Goldstone势的暴胀模型,这些模型适用于不同的背景:平坦闵可夫斯基、反德西特和非对称时空.在这个框架中,暴胀子势是自然平坦的,由于移位对称性和与之相关的质量尺度与5D几何量有关。

英文摘要:

In light of the five-year data from the Wilkinson Microwave Anisotropy Probe (WMAP), we discuss models of inflation based on the pseudo Nambu-Goldstone potential predicted in five-dimensional gauge theories for different backgrounds: flat Minkowski, anti-de Sitter, and dilatonic spacetime. In this framework, the inflaton potential is naturally flat due to shift symmetries and the mass scales associated with it are related to 5D geometrical quantities.
