Generalized hybrid natural inflation
arXiv:2305.03905 · doi:10.1103/PhysRevD.108.043514
Abstract
Although the hybrid natural inflation is a successful inflation model, the symmetry breaking scale in the model should be large for a negative value of the running of the scalar spectral index. This study proposed a generalized hybrid natural inflation model that can realize a low-scale inflation with a negative value of the running of the scalar spectral index.
