\pt-differential per-event yield of prompt \Xiczero (left) and \Xicplus (right) baryons measured in the different multiplicity classes in pp collisions at $\sqrt{s}=13$ TeV at midrapidity ($|y| 0.5$), along with the corresponding ratios to the multiplicity-integrated (INEL $>$ 0) class in the bottom panel. The values shown in the legend, denoted as $\left \dndeta \right>_{|\eta|0.5}$, correspond to the average charged-particle multiplicity at midrapidity for the respective multiplicity classes, as introduced in Table \ref{tab:multiplicity class}. The statistical and systematic uncertainties are shown as bars and open boxes, respectively. The shaded boxes indicate the uncertainty of the branching ratio.
