超引力中动力学修正的非最小Higgs暴胀

Variants of Kinetically Modified Non-Minimal Higgs Inflation in Supergravity

C. Pallis

摘要:

我们考虑模型的混沌膨胀驱动的一个共轭对希格斯超场参与自发破缺的大统一对称性的规模假设其超对称值的实部。采用Kaehler势,其突出的移位对称部分与c-成比例,并且与c+成比例的微小违反包含在对数中,我们表明,暴胀观测值与最近的普朗克和Bicep 2/Keck阵列结果设置非常匹配,例如,0.0064<= c+/c-<1/N其中N=2或3是对数的前因子。这些前因子从它们的整数值以上的偏差也进行了探讨和山顶通货膨胀发生的区域是本地化的。此外,我们分析了两种不同的可能的稳定机制的非暴胀伴随的超场,一个绑在高阶项和一个只有二次项内的参数的对数与正前因子Ns<6。在所有情况下,暴胀可以达到次普朗克暴胀值与相应的有效理论保留微扰么正性普朗克尺度。

英文摘要:

We consider models of chaotic inflation driven by the real parts of a conjugate pair of Higgs superfields involved in the spontaneous breaking of a grand unification symmetry at a scale assuming its Supersymmetric value. Employing Kaehler potentials with a prominent shift-symmetric part proportional to c- and a tiny violation, proportional to c+, included in a logarithm we show that the inflationary observables provide an excellent match to the recent Planck and Bicep2/Keck Array results setting, e.g., 0.0064<= c+/c-<1/N where N=2 or 3 is the prefactor of the logarithm. Deviations of these prefactors from their integer values above are also explored and a region where hilltop inflation occurs is localized. Moreover, we analyze two distinct possible stabilization mechanisms for the non-inflaton accompanying superfield, one tied to higher order terms and one with just quadratic terms within the argument of a logarithm with positive prefactor Ns<6. In all cases, inflation can be attained for subplanckian inflaton values with the corresponding effective theories retaining the perturbative unitarity up to the Planck scale.
