  "abstract": "We consider prompt $J/ψ$, $χ_{cJ}$ and $η_c$ production in high energy $pp$ collisions in the framework of non-relativistic QCD. We apply high-energy factorization with taking into account tree-level next-to-leading order corrections to the production amplitudes. Using several CCFM-evolved gluon densities in the proton and a previously proposed matching scheme to merge the leading and higher-order contributions, we extract the long-distance matrix elements for the entire charmonium family from a simultaneous fit to available LHC data. We provide predictions for the transverse momentum spectra and relative production rates $σ(ψ^\\prime)/σ(J/ψ)$ and $σ(χ_{cJ})/σ(J/ψ)$ and find them to be in good agreement with the LHC data within the theoretical and experimental uncertainties across a wide kinematic region. We demonstrate that taking into account the tree-level NLO corrections improves the global description of the data.",
