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

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.
