# Measurement of J/{\psi} production in pp collisions at LHC energies with ALICE

## TL;DR

This paper presents measurements of J/ψ production in proton-proton collisions at LHC energies, analyzing transverse momentum and multiplicity dependencies, and comparing results with theoretical models.

## Contribution

It provides new experimental data on J/ψ production at 7 TeV and 13 TeV, including at forward rapidity, enhancing understanding of quarkonium production mechanisms.

## Key findings

- J/ψ production increases with charged-particle multiplicity.
- Results are consistent with certain theoretical models.
- First measurements at 13 TeV at forward rapidity.

## Abstract

An overview of ALICE results on the measurement of J/{\psi} production in pp collisions at $\sqrt{s}$ = 7 TeV collected during the LHC Run-1 period is presented, as well as first results at forward rapidity from pp collisions at $\sqrt{s}$ = 13 TeV collected during the LHC Run-2 period. In particular, the measurement of J/{\psi} production as a function of transverse momentum and charged-particle multiplicity are discussed and compared to theoretical model calculations.
