Measured correlation function versus the relative momentum $\ks$ for \mbox{$\kam$--p $\oplus$ $\kap$--$\pbar$} pairs in pp collisions at $\sqrt{s}$ = 13 TeV (left), in \mbox{40--60\%} centrality interval in \pPb collisions at \snn = 5.02 TeV (middle) and in \mbox{60--70\%} centrality Pb--Pb collisions at \snn = 5.02 TeV (right) . In all the panels, data are compared with the \chiEFT-based potential  with fixed (blue bands) and free (red bands) coupling weights.
