Prompt charmonia hadroproduction in High Energy Factorization with tree-level NLO corrections
We consider prompt $J/\psi$, $\chi_{cJ}$ and $\eta_c$ 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 t...
