Description

In relativistic heavy-ion collisions, a large number of light nuclei can be produced. Studying the production mechanism of light nuclei can help us understand the evolution process of relativistic heavy-ion collisions. There have been quite a lot of studies on stable light nuclei, while research on unstable light nuclei is still relatively lacking. Unstable light nuclei are fragile resonance state, and it will be provide different perspectives for understanding the dynamical evolution of heavy-ion collisions.

In this presentation, we propose a new method to extract the signals of unstable light nuclei in relativistic heavy-ion collision experiments, specifically $^{4}\rm{Li}$ and $^{5}\rm{Li}$. This method is based on the phase-shift analysis data from low-energy nuclear scattering experiments as well as the Lednicky-Lyuboshitz model, and partial wave analysis of the nuclear-nuclear final state interactions in heavy-ion collisions will be implemented. We will present the centrality, rapidity dependence of the yield ($dN/dy$), transverse momentum ($p_T$) spectra, and mean transverse momentum ($\langle p_T \rangle$) of $^{4}\rm{Li}$ and $^{5}\rm{Li}$ in Au+Au collisions at $\sqrt{s_{NN}}=3$ GeV.
