We outline a theoretical approach supporting strong phase transitions from normal nuclear matter to the deconfined quark-gluon plasma, in the equation of state (EOS) for compact star matter, from vanishing to moderately high temperatures that are accessible for BM(a)N and MPD experiments at NICA. We study the connection of such hybrid EOS with the mass-radius relation of cold compact stars,...

The measurement of low-energy cosmic antinuclei may reveal the existence of exotic processes such as dark-matter annihilation, since the production rate of these ions through ordinary secondary processes is very low. However, the lack of experimental data at low energies, where both the antinuclei production and inelastic cross sections are very poorly known, prevents precise predictions of...

Understanding the dynamics of hadrons with strangeness has received a lot attention over the past decades in connection with the study of exotic atoms, the analysis of strangeness production and propagation in particle and nuclear research facilities, and the investigation of the possible strange phases in the interior of neutron stars. One venue of interest in the field of strangeness is the...

In the primordial QGP filling the early Universe the abundant strangeness is in chemical equilibrium since the characteristic Hubble time constant $H^{-1}\simeq 1\mu s$. Upon hadronization near to $T=150$ MeV one may think that relatively short lived massive strange hadrons decay rapidly and strangeness disappears. However, using detailed balance considerations for inverse decay reactions...

Recent observation data of pulsar masses led us to estimate nuclear parameters, however, these predictions are strongly uncertain due to the masquarade problem. To resolve this we introduced, te maximmal-mass compact star scenario, and took into account data satisfying this criteria. We tested our method, applying the extended σ-ω model in the mean-field approximation at zero temperature and...
