Single-field D-type inflation in the minimal supergravity in light of Planck-ACT-SPT data
Yermek Aldabergenov, Sergei V. Ketov
The minimal supergravity framework is applied to a construction of new D-type single-field models of inflation in agreement with precision measurements of the cosmic microwave back…
Inflation in gravity models revisited after ACT
Sergei V. Ketov, Ekaterina O. Pozdeeva, Sergey Yu. Vernov
The gravity models of inflation are revisited in light of the recent observations of cosmic microwave background radiation by Atacama Cosmology Telescope (ACT) and DESI Coll…
Curvature corrections to Starobinsky inflation can explain the ACT results
Andrea Addazi, Yermek Aldabergenov, Sergei V. Ketov
We investigate the impact of curvature corrections to Starobinsky inflation in light of the latest observational results from the Atacama Cosmology Telescope (ACT). While the pure…
One-loop corrections to the E-type -attractor models of inflation and primordial black hole production
Daniel Frolovsky, Sergei V. Ketov
The one-loop corrections (1LC) to the power spectrum of scalar perturbations arising from cubic interactions in the single-field E-type -attractor models of inflation and primor…
On Legacy of Starobinsky Inflation
Sergei V. Ketov
Alexei Alexandrovich Starobinsky was one of the greatest cosmologists of all times, who made fundamental contributions to gravitational theory and cosmology based on geometrical id…
Starobinsky inflation beyond the leading order
Shunsuke Toyama, Sergei V. Ketov
The Starobinsky model of cosmological inflation in four spacetime dimensions is reviewed with the emphasis on impact of quantum gravity corrections. As a specific example of the qu…
