 Measurements of bottomonium production in pp and PbPb collisions at $\sqrt{s_{\mathrm{NN}}\space}$ = 5.02 TeV / Oh, Geonhee (Chonnam Natl. U.) /CMS Collaboration Bottomonia are important probes of the quark-gluon plasma since they are produced at early times and propagate through the medium. The production cross sections of the three $\Upsilon$ states (1S, 2S, 3S) were measured by CMS in pp and PbPb collisions at $\sqrt{s_{\mathrm{NN}}\space}$ = 5.02 ${\mathrm{TeV}}\space$.
