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…
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…
Gauss-Bonnet-induced symmetry breaking/restoration during inflation
Yermek Aldabergenov, Daulet Berkimbayev
We propose a mechanism of symmetry breaking or restoration that can occur in the middle of inflation due to the coupling of the Gauss-Bonnet term to a charged scalar. The Gauss-Bon…
More on gravitational waves from double monodromy inflation
Medeu Abishev, Aigerim Abylayeva, Andrea Addazi +2
We further analyze phenomenological implications of double axion monodromy inflation proposed in Ref. Phys. Rev. D 104, L081302 (2021), in gravitational wave physics. We show that…
Nilpotent superfields for broken abelian symmetries
Yermek Aldabergenov, Auttakit Chatrabhuti, Hiroshi Isono
We find new solutions to real cubic constraints on chiral superfields transforming under global abelian symmetries. These solutions describe the low-energy dynamics of a gold…
Primordial black holes from modified supergravity
Yermek Aldabergenov, Andrea Addazi, Sergei V. Ketov
The modified supergravity approach is applied to describe a formation of Primordial Black Holes (PBHs) after Starobinsky inflation. Our approach naturally leads to the two-(scalar)…
