论文摘要

我们介绍了超级重力内的E-和T模型通胀的新颖实现,这些膨胀在很大程度上与Aftraton超级领域的动力学术语中分别与一根秩序的存在相关。该极是由于选定的对数kahler电位K而产生的,该电位K将与对数项的系数(-n)<0相关的标态曲率参数化双曲线歧管。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,在w的术语和预测0.001的张量比r之间的一些调整为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 present novel realizations of E- and T-model inflation within Supergravity which are largely associated with the existence of a pole of order one and two respectively in the kinetic term of the inflaton superfield. This pole arises due to the selected logarithmic Kahler potentials K, which parameterize hyperbolic manifolds with scalar curvature related to the coefficient (-N)<0 of a 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, 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.
