Web26 de fev. de 2024 · This cutoff scale guarantees the perturbative analysis of this model throughout inflation and preheating, alleviating the unitarity problem of single-field Higgs inflation [19, 26,27,28] . This additional \(R^2\) term can also be induced through quantum loop corrections in the large- \(\xi \) limit. Web11 de jul. de 2024 · During inflation, we investigated the effect of the large/small on the non-gaussianity. We found that large/small could not provide the large non-gaussianity. In this paper, we divided the preheating stage to be quadratic regime and quartic regime. During the quadratic regime, the gauge bosons production is the most dominant.
