Transverse momentum distributions of $\Xi^\pm$ per unit $\Delta\eta\Delta\varphi$ area in pp collisions at $\sqrt{s} = 13$ TeV. The left, central and right panels refer to full, transverse-to-leading and toward-leading production, respectively. Different colours refer to different multiplicity classes selected using the V0 detector, as indicated in the legend. The spectra are scaled by different factors to improve the visibility. The bottom panels display the ratios to the spectra measured in the 0-100% multiplicity class. The statistical errors are represented by the error bars, the systematic uncertainties by the empty boxes. Error bars are smaller than the marker size and are therefore not visible.
