From identical S- and P-wave $$p_\mathrm{T}$$ pT spectra to maximally distinct polarizations: probing NRQCD with $$\chi $$ χ states

Abstract A global analysis of ATLAS and CMS measurements reveals that, at mid-rapidity, the directly-produced $$\chi _{c1}$$ χc1 , $$\chi _{c2}$$ χc2 and J/$$\psi $$ ψ mesons have differential cross sections of seemingly identical shapes, when presented as a function of the mass-rescaled transverse...
