Measured \pXim (Top) and \pOm (Bottom) momentum correlation functions in \pp collisions at \mbox{$\sqrt{s}=13$~Te\kern-.1emV\xspace}~. The experimental data are shown as black symbols. The black vertical bars and the grey boxes represent the statistical and systematic uncertainties, and the square brackets show the $k^*$ bin width. The measurements are compared with theoretical predictions, shown as coloured bands, that assume either Coulomb or Coulomb+strong \HALQCD interactions. The width of the curves including \HALQCD predictions represents the uncertainty associated to the calculation and the grey shaded band represents the uncertainties associated with the determination of the source radius.
