二十面体暴胀引起的标量-张量混合

Scalar-tensor mixing from icosahedral inflation

Alberto Nicolis, Guanhao Sun

摘要:

研究二十面体暴胀中的混合纯量张量两点函数。在有效场论的有效范围内,这必须是微扰很小的;特别是,比标量谱小得多。然而,它可以比张量谱本身大得多。我们讨论了宇宙微波背景辐射温度-偏振谱的观测意义。

英文摘要:

We study the mixed scalar-tensor two-point function in icosahedral inflation. Within the regime of validity of the effective field theory, this has to be perturbatively small; in particular, much smaller than the scalar spectrum. However, it can be much bigger that the tensor spectrum itself. We discuss observational implications for the CMB temperature-polarization spectrum.
