Analytic extensions of Starobinsky model of inflation
Vsevolod R. Ivanov, Sergei V. Ketov, Ekaterina O. Pozdeeva +1
We study several extensions of the Starobinsky model of inflation, which obey all observational constraints on the inflationary parameters, by demanding that both the inflaton scal…

Exploring the parameter space of modified supergravity for double inflation and primordial black hole formation
Ryotaro Ishikawa, Sergei V. Ketov
We study the parameter space of the effective (with two scalars) models of cosmological inflation and primordial black hole (PBH) formation in the modified supergravity.…
