The relative yields of ϒ mesons produced in pp and Pb-Pb collisions at ffiffiffiffiffiffiffi sNN p ¼ 5.02 TeV and reconstructed via the dimuon decay channel are measured using data collected by the CMS experiment. Double ratios are formed by comparing the yields of the excited states, ϒð2SÞ and ϒ...
