From prompt to direct J/$\psi$ production: new insights on the $\chi_{c1}$ and $\chi_{c2}$ polarizations and feed-down contributions from a global-fit analysis of mid-rapidity LHC data
While the prompt $\mathrm{J}/\psi $ cross section and polarization have been measured with good precision as a function of transverse momentum, $p_\mathrm{T}$, those of the directly produced $\mathrm{J}/\psi $ are practically unknown, given that the cross sections and polarizations of the $\chi _{{c...
