Abstract
We consider a gedanken experiment of the scattering of a current off a large nucleus to study the gluon saturation at the small- limit and compute the Sudakov factor of this process through a one-loop calculation. The differential cross section is expressed in terms of the Sudakov resummation, in which the collinear and the rapidity divergences are subtracted.
