Description
We consider heavy quark pair production in high energy pp and pA collisions from the Color Glass Condensate (CGC) framework. The parton saturation is expected to characterize low-$P_\perp$ spectrum of the heavy quark pair production. Meanwhile, initial soft gluon radiation also can affect the low-$P_\perp$ spectrum.
Therefore, in order to study the parton saturation quantatively, both the small-$x$ resummation and the low-$P_\perp$ resummation have to be considered simultaneously.
In this talk, a brief review of the CGC framework will be presented first and then we will investigate the low-$P_\perp$ spectrum by considering initial soft gluon emission.
