Figure Caption
Top: Excited-to-ground state self-normalized yield ratio ($\Upsilon$(2S) over $\Upsilon$(1S)) as a function of self-normalized charged-particle multiplicity, compared to model predictions from 3-pomeron CGC approach~, PYTHIA~8.2~, comovers~, and CPP~ calculations. Bottom: Excited-to-ground state self-normalized yield ratio ($\Upsilon$(3S) over $\Upsilon$(1S)) as a function of self-normalized charged-particle multiplicity, compared to PYTHIA~8.2 and comovers predictions. The vertical error bars represent the statistical uncertainty, while the systematic uncertainties are depicted as boxes.
