      abstract     = {The production of J/ψ is measured as a function of
                      charged-particle multiplicity at forward rapidity in
                      proton-proton (pp) collisions at center-of-mass energies $
                      \sqrt{s} $ = 5.02 and 13 TeV. The J/ψ mesons are
                      reconstructed via their decay into dimuons in the rapidity
                      interval (2.5 < y < 4.0), whereas the charged-particle
                      multiplicity density (dN$_{ch}$/dη) is measured at
                      midrapidity (|η| < 1). The production rate as a function of
                      multiplicity is reported as the ratio of the yield in a
                      given multiplicity interval to the multiplicity-integrated
                      one. This observable shows a linear increase with
                      charged-particle multiplicity normalized to the
                      corresponding average value for inelastic events
                      (dN$_{ch}$/dη/〈dN$_{ch}$/dη〉), at both the colliding
                      energies. Measurements are compared with available ALICE
                      results at midrapidity and theoretical model calculations.
                      First measurement of the mean transverse momentum
                      (〈p$_{T}$〉) of J/ψ in pp collisions exhibits an
                      increasing trend as a function of
                      dN$_{ch}$/dη/〈dN$_{ch}$/dη〉 showing a saturation
                      towards high charged-particle multiplicities.},
