The multi-parameter character of supersymmetric dark-matter models implies the combination of their experimental studies with astrophysical and cosmological probes. The physics of the early Universe provides nontrivial effects of non-equilibrium particles and primordial cosmological structures. Primordial black holes (PBHs) are a profound signature of such structures that may arise as a cosmological consequence of supersymmetric (SUSY) models. SUSY-based mechanisms of baryosynthesis can lead to…

Cosmoparticle Physics of Dark Universe
The physics of the dark Universe goes beyond the standard model (BSM) of fundamental interactions. The now-standard cosmology involves inflation, baryosynthesis and dark matter/energy corresponding
Cosmological Probes of Supersymmetric Field Theory Models at Superhigh Energy Scales
The lack of positive results in searches for supersymmetric (SUSY) particles at the Large Hadron Collider (LHC) and in direct searches for Weakly Interacting Massive Particles (WIMPs) in the
Gravitational waves and primordial black holes from supersymmetric hybrid inflation
We study the effect of supergravity corrections due to a linear and a squared term in the Kähler potential, in the context of a supersymmetric hybrid inflation model. By appropriate choice of the
Cosmological consequences of theories of modified gravity
Our theoretical understanding of the dynamical evolution of the Universe has certainly improved during the recently established era of precision cosmology. However, the nature of the dark sector
Physics of superheavy dark matter in supergravity
New trends in inflationary model building and dark matter production in supergravity are considered. Starobinsky inflation is embedded into 𝒩 = 1 supergravity, avoiding instability problems, when
Extending Starobinsky inflationary model in gravity and supergravity
We review some recent trends in the inflationary model building, the supersymmetry (SUSY) breaking, the gravitino Dark Matter (DM) and the Primordial Black Holes (PBHs) production in supergravity.
Gravitino and Polonyi production in supergravity
We study production of gravitino and Polonyi particles in the minimal Starobinsky-Polonyi $$\mathcal {N}=1$$N=1 supergravity with inflaton belonging to a massive vector supermultiplet. Our model has
Multimessenger Probes for New Physics in the Light of A. Sakharov’s Legacy in Cosmoparticle Physics
The modern, standard cosmological scenario, which reflects, to a large extent, the development of A. D. Sakharov’s legacy in cosmoparticle physics, involves inflation, baryosynthesis and dark
Dark Matter from Starobinsky Supergravity
We review our recent results on dark matter from Starobinsky supergravity. In this context, a natural candidate for Cold Dark Matter is the gravitino. On the other hand, assuming the supersymmetry
