From identical S- and P-wave pT/M spectra to maximally distinct polarizations: probing NRQCD with chi states

A global analysis of ATLAS and CMS measurements reveals that, at mid-rapidity, the directly-produced ${\chi }_{c1}$, ${\chi }_{c2}$ and J/$\psi$ mesons have differential cross sections of seeming…
