    abstract = "Measurements of the inclusive J/psi yield as a function of
charged-particle pseudorapidity density dN(ch)/d eta in pp collisions at
root s = 13 TeV with ALICE at the LHC are reported. The J/psi meson
yield is measured at midrapidity (vertical bar y vertical bar < 0.9) in
the dielectron channel, for events selected based on the
charged-particle multiplicity at midrapidity (vertical bar eta vertical
bar < 1) and at forward rapidity (-3.7 < eta < -1.7 and 2.8 < eta <
5.1); both observables are normalized to their corresponding averages in
minimum bias events. The increase of the normalized J/psi yield with
normalized dN(ch)/d eta is significantly stronger than linear and
dependent on the transverse momentum. The data are compared to
theoretical predictions, which describe the observed trends well, albeit
not always quantitatively. (C) 2020 European Organization for Nuclear
