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 seemingly identical shapes, when presented as a function of the mass-rescaled transverse momentum, $p_\mathrm{T}/...
