三型和一型的各向异性

The anisotropy of a three- and a one-form

Federico R Urban

摘要:

我们计算了三重态与阿贝尔矢量规范场耦合的各向异性信号。在最简单的三种形式暴胀的例子中,矢量涨落的放大是指数的;这使得几乎可以肯定会产生大的各向异性,严重限制了耦合的可行性。

英文摘要:

We calculate the anisotropic signal associated with the coupling of a three-form with an Abelian vector gauge field. In the simplest examples of three-form inflation the amplification of the vector fluctuations is exponential; this makes it almost certain that a large anisotropy will develop, severely constraining the viability of the coupling.
