论文摘要
我们研究了二十面体膨胀中的混合标量调整两点功能。在有效田间理论的有效性方面，这必须在扰动上很小。特别是，比标量光谱小得多。但是，张量频谱本身可能会更大。我们讨论了对CMB温度极化光谱的观察意义。
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.
