Strong suppression of $\varUpsilon$ excited states in PbPb collisions at $\sqrt{s_{NN}} = 5.02~\mathrm{TeV}$

Measurements of $\varUpsilon$ mesons, produced in pp and PbPb collisions at $\sqrt{s_{NN}} = 5.02~\mathrm{TeV}$ and reconstructed via their dimuon decay channel, are reported using data collected by the CMS experiment. Double ratios are formed by comparing the yields of the excited states to the gro...
