Inclusive $\psi$(2S)-to-J/$\psi$ cross section ratio (left) and J/$\psi$, $\psi$(2S), $\Upsilon$(1S), $\Upsilon$(2S), and $\Upsilon$(3S) $p_{\rm T}$-integrated cross section per unit of rapidity (right) as a function of the collision energy in pp collisions [9, 11–13]. In the left panel, the systematic boxes include the BR uncertainties from both resonances, on top of the MC input and signal extraction systematic uncertainties. The 13 TeV data point is computed from the published individual J/$\psi$ and $\psi$(2S) $p_{\rm T}$-integrated cross sections. The statistical and systematic uncertainties are assumed to be uncorrelated between the resonances when computing the ratio. In the right panel, the luminosity and branching ratio uncertainties are included in the systematic boxes. The data are compared with theoretical calculations from ICEM + FONLL[47,49].
