Forward $\chi_c$ production in $pp$ and $pA$ collisions within the CGC+NRQCD framework

We study the forward $\chi_{cJ}$ production in the low $p_{\perp}$ region in proton-proton $(pp)$ and proton-nucleus $(pA)$ collisions at the LHC within the framework of non-relativistic QCD (NRQCD) factorization and the Color Glass Condensate (CGC) effective field theory. Incorporating the small-$x$ gluonic evolution...
