The ratio between the prompt $\ensuremath{\psi}(2S)$ and $J/\ensuremath{\psi}$ yields, reconstructed via their decays into ${\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$, is measured in Pb-Pb and $p$-$p$ collisions at $\sqrt{{s}_{NN}}=2.76\text{ }\text{ }\mathrm{TeV}$. 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\text{ …
