We discuss measurements of event-by-event relative hadron yield fluctuations with the νdyn observable in Pb — Pb collisions at sNN = 2.76 TeV. Fluctuation measurements presented include the relative yield of charged hadrons, the relative yield of identified pions (π) vs. kaons (K), π vs. protons (p) , K vs. p, as well as the more recent measurements of fluctuations of K+ vs. K− yields and...
The isospin-dependent equation of state of nuclear matter, i.e. symmetry energy $E_{sym}(\rho)$ plays an important role in the study of nuclear physics and Astrophysics. In terrestrial lab, heavy ion collision provides a unique way to constrain $E_{sym}(\rho)$. So a compact spectrometer for heavy ion experiment（CSHINE）is built and particle correlation functions are measured.
The HBT...
The OSCAR array (hOdoscope of Silicons for Correlations and Analysis of Reactions) is a modular detector aimed at studying two- and multi-particle correlation measurements in heavy-ion collisions and direct nuclear reactions at low beam energies. The main features of the OSCAR detector will thus be presented, including its present and future scientific programs.
Correlation measurements with...
The CHIFAR experiment was proposed to study the emission probability of Intermediate Mass Fragments (IMFs) in non-central Heavy Ion collisions. This phenomenon is linked to the features of the Equation of State of the nuclear matter, focusing also on the role of the isospin degree of freedom of the colliding nuclei. The CHIMERA collaboration has investigated three nuclear reactions at the...

Nowadays, the three-nucleon force is considered essential within the framework of nuclear forces. Additionally, three-hadron forces are thought to have a notable impact on hadronic systems beyond many-nucleon systems. The correlation function involving the deuteron and hadrons has emerged as a potential tool for exploring the three-hadron force. However, a comprehensive understanding of this...
High compression of nuclear matter occurs in central energetic collisions of heavy nuclei, commonly referred to just as Heavy Ion Collisions (HIC). Inferring the nuclear Equation of State (EoS) requires a careful selection of observables from HIC and comparisons to transport model simulations incorporating different EoS. Current status and plans on both the experimental and theoretical sides...
In the context of heavy-ion collisions, low relative-velocity two-particle correlations play a pivotal role in understanding the space-time characteristics of particle emission. These characteristics are typically represented by a relative emission source, which is determined through the Koonin-Pratt (KP) convolution formula, utilizing the relative wave-function of the particles. Previous...
We develop a kinetic approach to the production of light nuclei up to mass number A = 4 in intermediate-energy heavy-ion collisions by including them as dynamic degrees of freedom. The conversions between nucleons and light nuclei during the collisions are incorporated dynamically via the breakup of light nuclei by a nucleon and their inverse reactions. We also include the Mott effect on light...
