The femtoscopy analysis of the p - Λ system obtained in heavy-ion collisions within the HADES experiment

Abstract

Abstract. The study investigates hyperons in dense matter, addressing the “hyperon puzzle" and its implications for neutron stars. Utilizing femtoscopy in Ag-Ag heavy-ion collisions at 1.58 AGeV within the HADES experiment, the analysis focuses on Λ (uds) strange quarks. By reconstructing Lambdas through Λ → π− + p decay, the study measures the p - Λ correlation function, revealing a distinct peak and providing valuable insights into strong interaction parameters. The initial exploration of the nucleon-hyperon (N-Y) femtoscopic correlation signal is presented, with a focus on the ongoing nature of the contribution as a work in progress.
