Higgs boson mass and thermal wino dark matter from Starobinsky supergravity with the MSSM
Daniel Frolovsky, Alexander Belyaev, Sergei V. Ketov
We propose a framework connecting cosmic microwave background (CMB) observables with high-energy particle phenomenology, based on Starobinsky supergravity coupled to the Minimal Su…

Are single-field models of inflation and PBHs production ruled out by ACT observations?
Daniel Frolovsky, Sergei V. Ketov
The data release from the Atacama Cosmology Telescope (ACT) imposes stronger constraints on primordial black holes (PBHs) formation in single-field inflation models versus the Plan…

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…
