Induced Multi-phase Inflation with Reheating: Leptogenesis and Dark Matter Production in Metric versus Palatini
Nilay Bostan, Rafid H. Dejrah, Anish Ghoshal +1
We study non-minimally coupled scalar-induced multi-phase inflation in metric and Palatini gravity, considering linear, Brans-Dicke-like, and Higgs-like sectors. The scalar spectra…

Inflation in the Scale Symmetric Standard Model and Weyl geometry
Z. Lalak, P. Michalak
This work explores the possibility of inflation in a scale-symmetric extension of the Standard Model Higgs sector, where the Higgs field is coupled to a singlet scalar, the…
