Figure 2

Left: $\psi$(2S) production cross sections shown as a function of $\langle N_{\rm coll}\rangle$ for both p-Pb and Pb-p collisions. Right: ${\rm B.R.}_{\psi(\rm 2S)\rightarrow\mu^+\mu^-}\sigma_{\psi(\rm 2S)}/{\rm B.R.}_{{\rm J}/\psi\rightarrow\mu^+\mu^-}\sigma_{{\rm J}/\psi}$ shown as a function of $\langle N_{\rm coll}\rangle$ and compared to the pp value (line), with a band representing its uncertainty In both figures, vertical error bars correspond to statistical uncertainties, while the open boxes represent the systematic uncertainties. The Pb-p points are slightly shifted in $\langle N_{\rm coll}\rangle$ to improve visibility.
