The tensor-to-scalar ratio in punctuated inflation
Scalar spectra which exhibit a sharp drop in power at length scales corresponding to the Hubble radius today are known to lead to a better fit of the observed Cosmic Microwave Background (CMB) anisotropies, when compared to the conventional, featureless, power law spectrum. Recently, we have shown that scalar spectra with lower power on large scales naturally occur in punctuated inflation, i.e....
متن کاملSupersymmetric Hybrid Inflation
The non-supersymmetric and supersymmetric versions of hybrid inflation are summarized. In the latter, the necessary inclination along the inflationary trajectory is provided by radiative corrections. Supersymmetric hybrid inflation (with its extensions) is an extremely ‘natural’ inflationary scenario. The reasons are that it does not require ‘tiny’ parameters, its superpotential has the most ge...
متن کاملLeptogenesis in Supersymmetric Hybrid Inflation
The nonsupersymmetric as well as the supersymmetric hybrid inflationary model is reviewed. The scenario of baryogenesis via a primordial leptogenesis is discussed and the role of the nonperturbative electroweak sphaleron effects is analyzed in detail. A supersymmetric model based on a left-right symmetric gauge group, which ‘naturally’ leads to hybrid inflation, is presented. The μ problem is s...
متن کاملPreheating in Supersymmetric Hybrid Inflation
We study preheating in a general class of supersymmetric hybrid inflation model. Supersymmetry leads to only one coupling constant in the potential and thus only one natural frequency of oscillation for the homogeneous fields, whose classical evolution consequently differs from that of a general (non-supersymmetric) hybrid model. We emphasise the importance of mixing effects in these models whi...
متن کاملPost - inflation increase of the cosmological tensor - to - scalar perturbation ratio
We investigate the possibility that the amplitude of scalar density perturbations may be damped after inflation. This would imply that CMB anisotropies do not uniquely fix the amplitude of the perturbations generated during inflation and that the present tensor-to-scalar ratio might be larger than produced in inflation, increasing the prospects of detection of primordial gravitational radiation...
