Observation of sequential $\Upsilon$ suppression in PbPb collisions
The sequential suppression of the individual $\Upsilon$ states in PbPb collisions with respect to their yields in $pp$ data has been measured. The PbPb and $pp$ datasets used in these proceedings correspond to integrated luminosities of 150/$\mu$b and 230/nb, respectively, collected by the CMS exper...
