Abstract: The ratio between the prompt ?(2S) and J/? yields, reconstructed via their decays into µ+µ-, is measured in Pb-Pb and p-p collisions at vsNN=2.76??TeV. The analysis is based on Pb-Pb and p-p data samples collected by CMS at the Large Hadron Collider, corresponding to integrated luminosities of 150??µb-1 and 5.4??pb-1, respectively. The double ratio of measured yields (N?(2S)/NJ/?)Pb-Pb/(N?(2S)/NJ/?)p-p is computed in three Pb-Pb collision centrality bins and two kinematic ranges: one at midrapidity, |y|<1.6, covering the transverse momentum range 6.5
