Top: Self-normalized yield of $\Upsilon$ as a function of self-normalized charged-particle multiplicity, compared to inclusive J/$\psi$ measured in the forward rapidity region at $\s = 5.02$ TeV , $7$ TeV , and $13$ TeV , and to inclusive J/$\psi$ measured in the central rapidity region at $\s = 13$ TeV . Bottom: Self-normalized yield ratio of $\Upsilon$(1S)-to-J/$\psi$ as a function of self-normalized charged-particle multiplicity, compared to model computations from 3-pomeron CGC approach , PYTHIA 8.2 , comovers , and CPP  The vertical error bars represent the statistical uncertainty, while the systematic uncertainties on are depicted as boxes.
