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.
