abstract = {The measurement of ϒ(1S), ϒ(2S), and ϒ(3S) yields as a
function of the charged-particle multiplicity density,
dNch/dη, using the ALICE experiment at the LHC, is reported
in pp collisions at $\sqrt{s}$ = 13 TeV. The ϒ meson yields
are measured at forward rapidity (2.5 < y<4) in the dimuon
decay channel, whereas the charged-particle multiplicity is
defined at central rapidity (|η|<1). Both quantities are
divided by their average value in minimum bias events to
compute the self-normalized quantities. The increase of the
self-normalized ϒ(1S), ϒ(2S), and ϒ(3S) yields is found
to be compatible with a linear scaling with the
self-normalized dN$_{ch}$/dη, within the uncertainties. The
self-normalized yield ratios of excited-to-ground ϒ states
are compatible with unity within uncertainties. Similarly,
the measured double ratio of the self-normalized ϒ(1S) to
the self-normalized J/ψ yields, both measured at forward
rapidity, is compatible with unity for self-normalized
charged-particle multiplicities beyond one. The measurements
are compared with theoretical predictions incorporating
initial or final state effects.},
