Constraining the dense nuclear matter equation of state (EOS) has been the goal of numerous theoretical and experimental efforts worldwide. Recent advancements include inferences from observations of neutron stars and neutron star mergers, measurements of neutron skins, and various theoretical developments.
This makes complementary efforts relying on models of relativistic heavy-ion...
Ground state nuclei usually have compact geometries. However, there have been theoretical predictions that excited nuclei can take on more extended shapes such as toroids or bubbles. There have been many attempts to identify signatures of such shapes in experimental data. One signature both predicted by theory and reported in experimental data is narrow resonances at high excitation energy...
Light nuclear clusters are expected to be ubiquitously present in astrophysical environments and play an important role in different astrophysical phenomena involving ultra-dense baryonic matter, but the estimation of their abundancy demands to correctly estimate the in-medium modification of their binding energy.
In the original measurements, Equilibrium Constants were extracted detecting...
The nuclear incompressibility parameter, K$_{\infty}$, is an important component characterizing the nuclear equation of state, with crucial bearing on diverse nuclear and astrophysical phenomena. The only direct experimental measurement of this quantity comes from the compression-mode giant resonances--the isoscalar giant monopole resonance (ISGMR) and the isoscalar giant dipole...
PREX 2 and CREX, recently completed at Jefferson Lab in Newport News, Va, measured the weak form factors of lead and calcium. The PREX 2 result has confirmed that the neutron skin of lead is relatively large and has provided a precise determination of the interior baryon density of a heavy nucleus. The CREX measurement was performed at a non-optimal momentum transfer and has produced a...
Heavy-ion collisions is a unique tool for studying thermodynamical properties of nuclear matter. In particular, the study of clusters is a key ingredient in better understanding and constraining the nuclear equation of state. During the collision, the system is expected to undergo a compression followed by expansion, while a copious number of light and intermediate clusters are emitted [1]....
Our knowledge of the properties of dense nuclear matter is usually obtained indirectly via nuclear experiments, astrophysical observations, and nuclear theory calculations. Advancing our understanding of the nuclear equation of state (EOS, which is one of the most important properties and of central interest in nuclear physics) has relied on various data produced from experiments and...
The nuclear equation of state plays a central role for the physics of nuclei and dense matter in neutron stars. We discuss constraints on the equation of state from nuclear theory, experiments, and observations, focusing on neutron-rich conditions. On the theory side, we present chiral effective field theory calculations for arbitrary proton fraction and temperature using a Gaussian process...
Heavy-ion collisions in the Fermi energy regime are widely used to probe the properties of nuclear matter far from equilibrium: among other topics, they allow to investigate isospin transport phenomena, which can be interpreted in the framework of the Nuclear Equation of State. The INDRA-FAZIA apparatus [1], operating in GANIL, features the best characteristics to study such kind of phenomena,...
Determination of equation of state (EoS) for nuclear matter at high baryon density region is a topic of current interest in high-energy heavy-ion collisions and astrophysics. The pion/kaon HBT correlation (also called HBT interferometry) and intermittency are sensitive probes of the nuclear EoS. Within the UrQMD framework, it is found that the correlations of protons, correlated proton pairs...
