论文摘要

我们展示了如何在充气扇区的动力学混合中一两个阶的存在的情况下实施超级混乱的通货膨胀。该极是由于选定的对数kahler电位K而产生的,该电位K将双曲线歧管与标态曲率进行参数化,与对数项的系数-n相关。相关的超电势W具有与Aftraton-Acpany的超级场合相同的R电荷,并包含所有允许的术语。充气的角色可以由量规单线或非单曲超级场所扮演。在k中为k中一个对数项的模型需要n = 2,并且在w的项和预测0.001的张量比r之间的n = 2和一些调整为10^-5。对于更结构化的k,可以完全避开调整,而n值随着R和光谱指数接近甚至等于其当前的中央观察值而增加。

We show how we can implement within Supergravity chaotic inflation in the presence of a pole of order one or two in the kinetic mixing of the inflaton sector. This pole arises due to the selected logarithmic Kahler potentials K, which parameterize hyperbolic manifolds with scalar curvature related to the coefficient -N of the logarithmic term. The associated superpotential W exhibits the same R charge with the inflaton-accompanying superfield and includes all the allowed terms. The role of the inflaton can be played by a gauge singlet or non-singlet superfield. Models with one logarithmic term in K for the inflaton, require N=2 and some tuning, of the order of 10^-5, between the terms of W and predict a tensor-to-scalar ratio r at the level of 0.001. The tuning can be totally eluded for more structured K's, with N values increasing with r and spectral index close or even equal to its present central observational value.
