论文摘要
我们考虑了一两个阶的动力极对杂交膨胀的非苏匹配模型的影响。这些极点是由于对数的kaehler电势而产生的，该电位控制着充气场的动力学混合并参数化与对数系数（-n）<0相关的标量曲率的双曲线歧管。通货膨胀与局部SU（2）XU（1）对称性的破坏有关，后者不会产生任何宇宙学缺陷，并且在很大程度上仍然免受最小可能的辐射校正，从而对通货膨胀潜力产生最小的辐射校正。对于n = 1和相关耦合常数的相等值，lambda和kappa的实现NS的观察中心值的实现需要质量参数，M和对称性断裂量表M，分别为10^12 GEV和10^17 GEV的顺序。 n以上N以上n增加了张量比r的比率r升高到0.002以上，并达到n〜10-20的最大允许值。
We consider the impact of a kinetic pole of order one or two on the non-supersymmetric model of hybrid inflation. These poles arise due to logarithmic Kaehler potentials which control the kinetic mixing of the inflaton field and parameterize hyperbolic manifolds with scalar curvature related to the coefficient (-N)<0 of the logarithm. Inflation is associated with the breaking of a local SU(2)xU(1) symmetry, which does not produce any cosmological defects after it, and remains largely immune from the minimal possible radiative corrections to the inflationary potential. For N=1 and equal values of the relevant coupling constants, lambda and kappa, the achievement of the observationally central value of ns requires the mass parameter, m, and the symmetry breaking scale, M, to be of the order of 10^12 GeV and 10^17 GeV respectively. Increasing N above unity the tensor-to-scalar ratio r increases above 0.002 and reaches its maximal allowed value for N~10-20.
