  In this paper, we compute a number of cross sections for the production of
multiple particles at mid-rapidity in the semi-dilute / dense regime of the
color-glass condensate (CGC) effective field theory. In particular, we present
new results for the production of two quark-antiquark pairs (whether the same
or different flavors) and for the production of one quark-antiquark pair and a
gluon. We also demonstrate the existence of a simple mapping which transforms
the cross section to produce a quark-antiquark pair into the corresponding
cross section to produce a gluon, which we use to obtain various results and to
cross-check them against the literature. We also discuss hadronization effects
in the heavy flavor sector, writing explicit expressions for the production of
various combinations of $D$ and $\bar D$ mesons, $J/\psi$ mesons, and light
hadrons. The various multiparticle cross sections presented here contain a
wealth of information and can be used to study heavy flavor production,
charge-dependent correlations, and "collective" flow phenomena arising from
initial-state dynamics.
