Top panel: the correlation of primary charged particle $\pt$ spectra with multiplicity per $\nch > 0$ event for pp collisions at $\sqrt{s} = 5.02$ TeV. Bottom panels: the corresponding relative change of $\pt$ (left) and $\nch$ (right) distributions with respect to the inclusive ones. In the left panel, each of the curves represents a single $\nch$ value, ranging from $\nch = 1$ (blue) to $\nch = 55$ (red). In the right panel, the colours represent the $\pt$ intervals used in this analysis from the lowest in blue to the highest one in red.
