### Description

Heavy quark pair production in minimum bias p+p and p+A collisions has been studied extensively in the CGC framework and compared successfully to both the RHIC and LHC data on $J/\psi$ production [1, 2], $\psi(2S)$ production [3] and $D$-meson production [4]. We first present an update in this framework based on comparisons to the latest LHC and RHIC data on p+p and light-heavy ion collisions. We will then present novel results [5] on extensions of these studies of Heavy Flavor and Quarkonia to rare events; this work, in completion, demonstrates that this framework captures the systematics of both Heavy-Flavor and Quarkonium production as a function of $N_{\rm charge}$ at both RHIC and the LHC. Finally, we will discuss the importance of Sudakov resummations in this framework to describe $\Upsilon$ production [6, 7].
