    \\large Femtoscopy is a powerful technique used to investigate the emission source and interaction potential between pairs of particles. The two-particle correlation function, which reveals valuable information about the space-time evolution of the emitting source and final state interaction, is the primary observable of interest. A detailed knowledge of hyperon-nucleon (Y-N) interaction is important for understanding the equation of state of neutron star. In high energy heavy-ion collisions, a large number of particles including hyperons are produced, which offers the great opportunity to study those interactions via femtoscopic measurements.\

    \\large In this talk, we present the measurements of p-$\\Xi^\{-\}$ correlations with high statistics in Isobar collisions (Ru+Ru, Zr+Zr) at $\\sqrt\{s_\{\\mathrm\{NN\}\}\}$ = 200 GeV by the STAR experiment. By employing Lednicky-Lyuboshitz approach, the scattering length ($f_\{0\}$) and effective range ($d_\{0\}$) of proton and $\\Xi^\{-\}$ interactions are extracted. Results from Au+Au collisions at the same energy will be used for comparison. In addition, these parameters will be compared to those from Lattice QCD calculations.\
