Hypernuclei are bound states of nucleons and hyperons, and thus naturally correlated hyperon-baryon systems. Hypernuclei are regarded a unique laboratory to study the hyperon-nucleon ($Y$-$N$) interaction. The $Y$-$N$ interaction is an important ingredient, not only in the equation-of-state (EoS) of astrophysical objects such as neutron stars, but also in the description of the hadronic phase...

Hypernuclei are bound nuclear systems of correlated nucleons and hyperons. Therefore, the production of hypernuclei in heavy-ion collisions provides an experimental avenue for studying the hyperon$-$nucleon (Y-N) interaction, which is an important ingredient, not only in the equation-of-state (EoS) of astrophysical objects such as neutron stars but also in the description of the hadronic phase...

High energy heavy-ion collisions provide an opportunity to study the production mechanism of light (anti)nuclei. There are two main possible models to explain the production mechanism - the thermal model and the coalescence model. The thermal model has been quite successful in explaining the yields of light (anti)nuclei produced in heavy-ion collisions. Thermal model suggests that the light...

Multi-particle reactions in the late stages of heavy-ion collisions are demonstrated to be significant for the final deuteron [1] and proton [2] abundances at intermediate to high beam energies. They are realized by employing a stochastic collision criterion in the hadronic transport approach SMASH.
This work sheds light on the puzzle that both final-state coalescence from nucleons and...

The main goal of the CBM experiment at FAIR is to study the properties of nuclear matter at very high baryonic density, where an onset of the transition to a deconfined and chirally restored phase is expected to happen. The study of (multi-strange) hypernuclei production mechanism in high baryon density region of QCD phase diagram, determination of their lifetimes, decay branching ratios and...

Matter-antimatter asymmetry is a precondition necessary to explain the existence of our world made predominately of matter over antimatter. Antimatter is rare in the current universe making it difficult to study, but the Relativistic Heavy-Ion Collider (RHIC) provides us a unique opportunity to study antimatter with high-energy nuclear-nuclear collisions. In this poster, we report the...

The composition of the fireball produced in high-energy Pb-Pb collisions at the LHC can be described by the Grand Canonical Statistical Hadronisation Model (SHM). One of the parameters of the model is the baryon chemical potential $\mu_B$, which determines the fraction of antimatter and matter present in the gas. The hypothesis that at the LHC $\mu_{B}=0$, i.e. antimatter and matter are...

Production of light nuclei in relativistic heavy-ion collisions is well described by the thermal model, where light nuclei are in equilibrium with all other hadron species present in a fireball, and by the coalescence model, where light nuclei are formed due to final state interactions after the fireball decays. A method is proposed to falsify one of the models. We suggest to measure a...

This study confronts the idea of nuclei and hypernuclei formation within the thermal model description. We have employed a newly developed chemical freezeout (CFO) parametrization method and proposed some ratios of hadrons and nuclei. By varying the decay contribution into the hadrons, we have found that these light nuclei and hyper-nuclei states are formed near the CFO boundary, even before...

Light nuclei are the delicate probes of ultra-relativistic heavy ion collisions. Studying the light nuclei productions will help us to understand the nucleon emission source, the nucleosynthesis mechanism and the density fluctuations related to the critical point or first-order phase transition in heavy-ion collisions. In this talk, I will present our recent work about the beam energy...

Understanding light (anti-)nuclei production mechanism is a long-standing challenge in heavy-ion physics. Besides its own importance, it can benefit the search of QCD critical point as well as the detection of dark matter in space. In this presentation, we present a unified description of the microscopic dynamics of light (anti-)nuclei production in high-energy nuclear collisions by solving...
