Previous ALICE studies have shown a stronger than linear relative increase of the inclusive J/ψ production at mid-rapidity as a function of the mid-rapidity charged-particle multiplicity in proton-proton collisions. Studies on Monte Carlo simulations with PYTHIA 8 attributed this behavior to
autocorrelation effects. In this regard, interesting results were obtained studying the correlation of
the J/ψ production with the charged-particle multiplicity in different regions of the azimuthal angle
with respect to the flight direction of the J/ψ meson.
With experimental data on proton-proton collisions at √s=13 TeV, collected with ALICE during
Run 2 of data taking at the LHC, latest results of the relative J/ψ yield, measured at mid-rapidity
(|y|<0.9), in the di-electron decay channel, as a function of the charged-particle multiplicity will be
shown and compared to predictions from the PYTHIA8 Monte Carlo generator and other available
