Measurement of $J/\psi$ production as a function of event multiplicity in pp collisions at $\sqrt{s}=13\mathrm{TeV}$ with ALICE

Abstract

The availability at the LHC of the largest collision energy in pp collisions allows a significant advance in the measurement of $J/\psi$ production as function of event multiplicity. The interesting relative increase observed with data at the LHC at $\sqrt{s}=7\mathrm{TeV}$ and at RHIC at $\sqrt{s}=0.2\mathrm{TeV}$ is studied now at unprecedented multiplicities at $\sqrt{s}=13\mathrm{TeV}$. The measurement at mid-rapidity in the dielectron channel with ALICE is presented and discussed in comparison to predictions from available theoretical models and to data at lower energies.
