Proton-proton and proton-cluster femtoscopy at the HADES experiment

This work explores femtoscopic correlations in proton-proton and proton-cluster systems at the HADES experiment, GSI. Through high-precision correlation functions, it reveals the impact of strong interactions between protons and light nuclei (deuteron, triton, Helium-3). For proton-proton interactions, measurements in two centralities and five $k_T$ bins were analyzed. Extracted radii were compared with different Equations of State in UrQMD, providing valuable insights into collision dynamics. This research enhances our understanding of particle interactions and contributes to refining theoretical models in nuclear and particle physics.
