The properties of $\pi, \eta, K^+$ and $K^-$ mesons are studied in nuclear reactions from SIS to SPS energies within the covariant transport approach HSD in comparison to the experimental data. Whereas the pion, $\eta$ and kaon abundancies…
Properties of dense quark matter in and out of chemical equilibrium are studied within the SU(3) Nambu-Jona-Lasinio model. In addition to the 4-fermion scalar and vector terms the model includes also the 6-fermion flavour mixing…
In this work, we extract the QCD Equation of State (EoS) using experimental results of the $\phi$ meson produced in nuclear collisions at AGS, SPS and RHIC energies. The data are confronted to simple thermodynamic expectations and lattice…
Several boson exchange potentials, describing the NN interaction $T_\ell\le 300$ MeV with high quality, are extended in their range of applicability as NN optical models with complex local or separable potentials in r-space or as complex…
We study a production of Coulomb-assisted $\Sigma^-$-nucleus bound states by nuclear ($K^-$, $\pi^+$) reactions within a distorted-wave impulse approximation, so as to examine several types of the $\Sigma$-nucleus potentials that are…
The symmetry energy coefficients for nuclei with mass number A=20~250 are extracted from more than 2000 measured nuclear masses. With the semi-empirical connection between the symmetry energy coefficients of finite nuclei and the nuclear…
In the present work we explore the possibilities of the formation of bound states of neutral pseudoscalar mesons $\eta, \eta^{'}, D^{0}$, $\bar{D^{0}}, B^{0}, \bar{B^{0}}$ and $\bar{K^{0}}$ and the vector meson $\phi$, with the nuclei…
We observed a distinct peak in the $\Lambda p$ invariant mass spectrum of $^{3}{\rm He}(K^-, \, \Lambda p)n$, well below the mass threshold of $m_K + 2 m_p$. By selecting a relatively large momentum-transfer region $q = 350 \sim 650$…
Nuclear mass measurements and neutron matter theory tightly constrain the nuclear symmetry energy parameters $J$, $L$, $K_{sym}$ and $Q_{sym}$. Corroboration of these constraints on $J$ and $L$ can be found from measurements of the neutron…
We model J/psi using an effective lagrangian approach and calculate its spectral function in a gas of light mesons at finite temperature. We explore the hadronic landscape estimating cross sections for elastic and inelastic channels.…
We calculate the Equation of State of a quark system interacting through a phenomenological potential: the Richardson's potential, at finite baryon density and zero temperature. In particular we study three different cases with different…

Near-threshold data on meson production in nucleon-nucleon scattering are analysed in the short-range limit which permits a quantitative comparison of the production in two and three-body final states. The relative strengths of different…
The subthreshold photoproduction of \phi mesons from heavy nuclear targets has been suggested as a candidate to search for the \phi-N bound state, a quantum chromodynamics molecular state. In this Brief Report, we present detailed Monte…
