Higgsino dark matter in the Starobinsky supergravity with the MSSM in light of the LUX-ZEPLIN event
Daniel Frolovsky, Sergei V. Ketov
We realize a nearly pure higgsino dark matter candidate with mass of about 1 TeV in the Minimal Supersymmetric Standard Model coupled to the Starobinsky supergravity. The recent LU…
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…
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…
-term Multi-Field Inflation in Supergravity without Stabiliser Superfields
Jinn-Ouk Gong, Sergei V. Ketov, Takahiro Terada
Realising -term slow-roll inflation in supergravity is non-trivial due to the well-known -problem. The common strategy to solve the problem is to impose a shift symmetry on t…
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…
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…
