We review the physics of hyperons and Δ-resonances in dense matter in compact stars. The
covariant density functional approach to the equation of state and composition of dense …

Understanding the equation of state of dense nuclear matter is a fundamental challenge for
nuclear physics. It is an especially timely and interesting challenge as we have reached a …

We construct new effective interactions using the relativistic mean-field models with the
isoscalar-and isovector-meson mixing, σ 2 δ 2 and ω μ ω μ ρ ν ρ ν. Taking into account the …

The equation of state (EoS) and composition of dense and hot Δ-resonance admixed
hypernuclear matter is studied under conditions that are characteristic of neutron star binary …

Using the relativistic mean-field model with nonlinear couplings between the isoscalar and
isovector mesons, we study the properties of isospin-asymmetric nuclear matter. Not only the …

Theories of gravity in the beyond Horndeski class encompass a wide range of scalar-tensor
theories that will be tested on cosmological scales over the coming decade. In this work, we …

The so called hyperon puzzle, ie, the difficulty to reconcile the measured masses of neutron
stars (NSs) with the presence of hyperons in their interiors, is one of the hot topics in …

The hypernuclear matter is studied within the relativistic Hartree-Fock theory employing
several parametrizations of the hypernuclear density functional with density-dependent …

Background: At high density deconfinement of hadronic matter may occur leading to quark
matter. The immense densities reached in the inner core of massive neutron stars may be …

We propose and apply a new parametrization of the modified chiral effective model to study
rotating neutron stars with hyperon cores in the framework of the relativistic mean-field …
