The bulk nuclear matter produced in heavy ion collisions carries a multitude of conserved quantum numbers: electric charge, baryon number and strangeness. Therefore, the diffusion processes associated to these conserved charges cannot occur independently and must be described in terms of a set of coupled diffusion equations. This physics is implemented by replacing the traditional diffusion...

We review some results in quark matter and few nucleon systems using effective models for QCD and the nuclear force.

This work is devoted to the discussion of the ground state and the orbitally and radially excited states of quark-antiquark mesons within the Tamm-Dancoff approximation of the Coulomb-gauge QCD model. The Regge trajectories for angular and radial excitations are constructed, and their properties are analyzed. The calculated meson masses and their quantum numbers are used as basis to attribute...

We discuss properties of axial-vector mesons within an effective version of Quantum Chromodynamics in the Coulomb gauge. While recent studies have put emphasis in configuration mixing with open meson-meson channels, we here concentrate on the simpler closed-channel problem and follow the $1^+$ mixing through a wide range of quark masses. We also examine their radial excitations

and discuss...

The physics of short-ranged correlations is reviewed from a pedagogical standpoint that is aimed to provide background sufficient for students to do research in the field. The lectures discuss:

1) how the earliest efforts allowed physicists to understand the qualitative features of nuclear binding and saturation.

2) the technical improvements, including relativistic effects

3)...

The light mesons, like pion, play special rules in try to understanting QCD, between another motivation, the pion is the Goldstone boson, and, is central to symmetry breaking and partial current conservation

(PCAC). The most general way to take informations about the hadronic substructure, i.e.; in terms of the degrees of freedom from QCD, quarks and gluons, are the study of the...

We use the Monte Carlo particle physics code FLUKA to calculate gamma-ray spectra expected from solar flare energetic ion distributions. The FLUKA code includes robust physics-based models for electromagnetic, hadronic and nuclear interactions, sufficiently detailed for it to be a useful tool for calculating nuclear de-excitation, positron annihilation and neutron capture line fluxes and...

Abstract: Heavy mesons play an important role to understand the properties of strongly interacting matter. Quarkonia that survived after the quark-gluon plasma phase are expected to collide with other particles that constitute hadronic matter. In this work, we present a study on the interactions of the $\Upsilon$ meson with a hadronic medium. The meson-meson interactions are described by an...
