The LHC quarkonium production measurements reveal a startling observation:the J/$\psi$, $\psi$(2S), $\chi_{c1,2}$ and $\Upsilon$(nS) $p_{\rmT}$-differential cross sections are compatible with one universal momentumscaling pattern. Considering also the absence of strong polarizations ofdirectly and indirectly produced S-wave mesons, we are led to the conclusionthat there is currently no evidence of a dependence of the partonic productionmechanisms on the quantum numbers and mass of the final state. The experimentalobservations supporting this universal production scenario are remarkablysignificant, as shown by a new analysis approach, unbiased by specifictheoretical calculations of partonic cross sections, which are only considereda posteriori, in comparisons with the data-driven results.
