Deskripsi
Heavy-ion collisions provide a unique opportunity to explore nucleon-hyperon (N-Y) interactions through two-particle correlations. The p − Λ and d − Λ correlations shed light on both N-Y two-body and N-N-Y three-body interactions, which is crucial for understanding neutron star properties. We present the high precision measurement of p − Λ and the first measurement of d − Λ correlation with √SNN = 3 GeV Au+Au collisions at STAR. Using the Lednicky-Lyuboshitz formalism, we characterized emission source size, the scattering length (f0), and the effective range (d0) of p − Λ and d − Λ interactions. Using the f0 and d0 extracted from two spin states in d − Λ correlation, the parameters from the doublet state indicate the hypertriton binding energy is consistent with the current average of world measurements.
