Measurement of Nuclear Modification Factors of $\Upsilon\textrm{(nS)}$ Mesons in $\text{PbPb}$ Collisions at $\sqrt{s_{_{\text{NN}}}} = 5.02~\mathrm{TeV}$
The cross sections of $\Upsilon\textrm{(1S)}$, $\Upsilon\textrm{(2S)}$, and $\Upsilon\textrm{(3S)}$ production in PbPb and pp collisions at $\sqrt{s_{\mathrm{NN}}} = 5.02~\mathrm{TeV}$ are reported. The nuclear modification factors, $R_\mathrm{AA}$, derived from the PbPb-to-pp ratio of yields for ea...
