Description
The increase of hadronic production as a function of multiplicity in proton-proton and proton-lead collisions is considered as an interesting observable to study multi-parton interactions. The correlation between J/$\Psi$ production and multiplicity has been studied in pp collisions at $\sqrt{s} = 7$ and 13 TeV and p-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV by ALICE. An increase of the relative J/$\Psi$ yields with respect to the relative multiplicity has been observed.
In the present talk, results on the multiplicity dependence of the J/$\Psi$ production in pp collisions at $\sqrt{s}$ = 2.76 and 5.02 TeV, measured at forward rapidity, will be presented for the first time. Similar results for p-Pb collisions at $\sqrt{s_{\rm NN}} = 8.16$ TeV at forward rapidity will also be shown. Results will be compared to the available ALICE measurements obtained in pp collisions at $\sqrt{s}$ = 7 and 13 TeV and p-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV as well as with theoretical model predictions.
