The only way to study the properties of asymmetric nuclear matter at high densities in the laboratory conditions is to investigate the relativistic heavy ion collisions. A complementary source of information are the astrophysical observations and gravitational waves. The degree of compression and pressures achieved during the heavy ion collision depend on the susceptibility of the nuclear...

The CHIFAR experiment at the INFN-LNS coupled the 4$\pi$ CHIMERA multi-detector with 10 telescopes of the FARCOS (Femtoscope Array for COrrelations and Spectroscopy) correlator. FARCOS is a triple-stage telescope consisting of two DSSSDs (Double Sided Silicon Strip Detectors, 300 and 1500 $\mu$m thick) and 4 CsI(Tl) scintillators (6 cm thick), featuring high energy and angular resolution....

The study of the density dependence of the equation of state (EOS) of nuclear matter at supra-saturation densities is a major topic of modern nuclear physics, with important implications in many fields. These span from astrophysics, such as the behavior of neutron stars and core collapse supernovae, to heavy ion collision (HIC) phenomena. Symmetry energy can be investigated not only by means...

The effect of $N/Z$ has been probed through different processes such as reactions around the Fermi energy where nuclear dynamics is prominent. Alternatively, the fusion of two nuclei is a process where both the initial structure of the two nuclei and the collision dynamics can play an important role. Light nuclei in particular provide a rich testing ground for the interplay of nuclear...

Taking as a reference the system $^{40,48}$Ca$+^{40,48}$Ca at 35 $A$MeV, recently measured at Ganil with the VAMOS-INDRA setup [1], we build a microscopic simulation of neutron and proton currents characterising nuclear systems at Fermi energies.

In particular, we focus on the combination of collective and dissipative processes occurring at midrapidity, related to drifts and fluctuations, and... -

In March 2025, at the GSI laboratory in Germany, the ASY-EOS II experiment was conducted. The reaction ^{197}Au+^{197}Au was studied at beam energies of 280, 400, 600, and 1000 AMeV. The experiment was designed to investigate high-density nuclear matter and to provide a new and robust constraint on the symmetry energy term of the nuclear equation of state (EoS).

The nuclear symmetry energy and its density dependence, particularly above saturation density, remain among the most significant uncertainties in the nuclear equation of state (EoS). These properties play a crucial role in both intermediate-energy heavy-ion collisions and the structure of neutron star matter. Experimental information at supra-saturation densities, however, is still limited,...

A new method, based on comparing isotopic yield ratios measured at forward and sideward polar angles and on cross-bombarding heavy nuclei with different neutron-to-proton ratios, is used to quantify the stopping power of nuclear matter in heavy-ion collisions. For central collisions of isotopically separated 124,129Xe+112,124Sn at 100 MeV/nucleon bombarding energy, measured with the 4π...

Heavy ion collisions provide a unique laboratory for studying nuclear matter under extreme conditions. The mid-rapidity region, characterized by particles emitted perpendicular to the beam axis, shows experimentally a neutron enrichment. The isospin transport processes and the density-dependent behaviour of the symmetry energy affect the transport of nucleons to this region of interaction...
