Mutated hilltop inflation in light of Planck/ACT observations
Iraj Safaei, Soma Heydari, Milad Solbi +1
Here, a single field inflationary model driven by a mutated hilltop potential, a subclass of the hilltop models of inflation, is investigated. To constrain the parameter space, we…

Primordial black holes in SB SUSY Gauss-Bonnet inflation
A. Ashrafzadeh, M. Solbi, S. Heydari +1
Here, we explore the formation of primordial black holes (PBHs) within a scalar field inflationary model coupled to the Gauss-Bonnet (GB) term, incorporating the low-scale spontane…

Primordial black holes generated by fast-roll mechanism in non-canonical natural inflation
Soma Heydari, Kayoomars Karami
In this work, a new fast-roll (FR) mechanism to generate primordial black holes (PBHs) and gravitational waves (GWs) in generalized non-canonical natural inflation is introduced. I…
