Measured correlation function of \XiK pairs. Data are represented by the black circles, with statistical (black vertical lines) and systematic (orange boxes) uncertainties shown separately The pink and blue bands represent the results from the fit considering strong and Coulomb FSI via the LL approach and the BCN model, respectively The gray band represents the mini-jet background associated with the LL fit The green line represents the Coulomb-only assumption The lower panel presents the difference between the data and the modeled correlation functions for the LL (pink) and BCN (blue) models expressed as the number of standard deviations, n$\sigma$.
