  The LHC quarkonium production measurements reveal a startling observation:
the J/$\psi$, $\psi$(2S), $\chi_{c1,2}$ and $\Upsilon$(nS) $p_{\rm
T}$-differential cross sections are compatible with one universal momentum
scaling pattern. Considering also the absence of strong polarizations of
directly and indirectly produced S-wave mesons, we are led to the conclusion
that there is currently no evidence of a dependence of the partonic production
mechanisms on the quantum numbers and mass of the final state. The experimental
observations supporting this universal production scenario are remarkably
significant, as shown by a new analysis approach, unbiased by specific
theoretical calculations of partonic cross sections, which are only considered
a posteriori, in comparisons with the data-driven results.
