Description
We study the parton saturation effects on heavy quark production
in proton-nucleus collisions at collider energies, using the CGC
formula proposed by Blaizot-Gelis-Venugopalan (Nucl.Phys.A743:57-91,2004).
Previously it was numerically evaluated using the unintegrated
gluon distribution from the McLerran-Venugopalan model including
the x-evolution effect with the Balitsky-Kovchegov equation
(Fujii-Gelis-Venugopalan, Nucl.Phys.A780:146-174,2006).
Here we extend the phenomenological study by including the
running coupling effect in the x-evolution. We will investivate
the saturation effects on the quark and quark pair spectra, and
the quarkonium spectrum as well, at the RHIC and LHC energies.
