Short-range nucleon-nucleon correlations (SRC), fluctuations when nucleons form pairs with high relative momentum and small center of mass momentum for short periods of time, provide important information on large relative momentum and short distance properties of nuclear wave functions. This information is important in theoretical models to understand the density dependence of symmetry...
The equation-of-state (EoS) of nuclear matter is of fundamental interest and has been the object of intense theoretical efforts since several decades. The interest is boosted by the fact that it is an important ingredient in modelling astrophysical phenomena such as compact stars and core collapse supernovae. A method to approach the nuclear equation-of-state, practiced since the mid-eighties,...
Charged pion production in HIC is one of the possible probes to study the density dependent symmetry energy. In 2016, the experiments for the measurement of charged pion ratio in neutron-rich and in neutron-deficient Sn+Sn system at the beam energy of E/A=270 MeV were conducted at RIKEN-RIBF.
A constraint on the symmetry energy around the nuclear density of \rho ~ 1.5\rho_0 was given based on...
Heavy-ion collisions at intermediate energies (20-100 MeV/nucleon) are an essential tool for probing the properties of nuclear matter in far-from-equilibrium conditions. Among other topics, they allow the investigation of isospin transport phenomena, which can be interpreted within the framework of the Nuclear Equation of State (NEoS). This area of research holds significant interest due to...
One of the most exciting challenges in modern nuclear physics and astrophysics is to understand the behavior of nuclear matter under extreme conditions. Intermediate energy heavy-ion reactions provide a unique opportunity to enrich our knowledge about the nuclear equation of state (EoS) at sub-saturation densities [1,2]. In particular, the isospin transport in heavy-ion reactions at...
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...
Previous studies at the Cyclotron Institute at Texas A&M University have experimentally shown that neutron-proton equilibration in heavy-ion collisions evolves exponentially [1,2]. The two heaviest fragments originating from the dynamically deformed, excited projectile-like fragment evolve to become more similar as its angle of rotation increases. Results were compared to Constrained Molecular...
To study the pion production in heavy-ion collisions, we developed the transport model [1] which combines the nucleon dynamics obtained by the antisymmetrized molecular dynamics (AMD) model with a newly developed transport code which we call sJAM. In the previous work [1], we treated the collision terms of the $NN \leftrightarrow N \Delta$ and $\Delta \leftrightarrow N \pi$ processes with the...
