Average A-side ZN (left) and ZP (right) signals as a function of the C-side signals in pp collisions at $\sqrt{s} = $~13~TeV. Data (red full circles) are compared with model predictions from PYTHIA~6 (azure line), PYTHIA~8 (dashed blue line) and EPOS (dotted green line).

ZN (left) and ZP (right) asymmetry distributions for same (blue full circles) and mixed event distributions (blue open circles). In the bottom panels the difference between the uncorrelated and the correlated distributions is shown (red full squares) and compared to the simulation results using the three event generators (lines).

ZN energy normalised to the average MB value in the Pb-fragmentation (left) and in the p-fragmentation (right) regions as a function of centrality estimated from ZN~\cite{ALICEcentrpA} in p--Pb collisions at $\sqrt{s_{\rm{NN}}}=5.02$~TeV (pink circles) and $8.16$~TeV (blue squares). The boxes represent the systematic uncertainty.

Left: ZN spectrum in pp collisions at $\sqrt{s}=$13~TeV for the MB sample (blue circles) and in three multiplicity intervals: high (magenta squares), intermediate (orange squares) and low (azure squares) multiplicity. Right: ratio of the spectra, normalised to the number of events in each bin, in the three multiplicity intervals to the MB spectrum.

Self-normalised ZN signal (red circles) and number density $N_{ch}$ (azure squares) distribution in the transverse region (published in Ref.~\cite{ALICEue}) as a function of $\pt^{\rm leading}$ measured in $|\eta| <$0.8. Tracks have \pt$>$0.15~GeV/c, markers are placed at the centre and not at the average of the \pt leading bin.
