Query: Comprehensive description of $J/\psi$ production in proton-proton
  collisions at collider energies   We employ a small $x$ Color Glass Condensate (CGC)+ Non-Relativistic QCD
(NRQCD) formalism to compute $J/\psi$ production at low $p_\perp$ in
proton-proton collisions at collider energies. Very good agreement is obtained
for total cross-sections, rapidity distributions and low momentum $p_\perp$
distributions. Similar agreement is obtained for $\psi^\prime$ production. We
observe an overlap region in $p_\perp$ where our results match smoothly to
those obtained in a next-to-leading order (NLO) collinearly factorized NRQCD
formalism. The relative contribution of color singlet and color octet
contributions can be quantified in the CGC+NRQCD framework, with the former
contributing approximately $10\%$ of the total cross-section.
