Abstract
Heavy-ion collisions offer a unique way to study hyperon-nucleon (Y–N) interactions through two-particle momentum correlations, which reveal the source's space-time structure and the effects of the final state interactions. (Correlations between light nuclei (d, t, 3He) and A provide insight into hypernuclei structure, binding energies, and many-body interactions that might be relevant to the inner structure of neutron stars. This work presente the first measurements of d–Λ, t–Λ, and 3He–A correlation trem √sNN = 3 GeV Au+Au collisions colSeccted in 2021 at STAR. Using tire Lednicky-Lyuboshitre model, we exlract source sizes and interaction parameters, shedding light on hypraon interactions and light hypernuclei structure.
