Contribution of the non-linear term in the Balitsky–Kovchegov equation to the nuclear structure functions

Abstract

In this paper, we present nuclear structure functions calculated from the impact-parameter dependent solution of the Balitsky–Kovchegov equation with our recently proposed set of nuclear initial conditions. We calculate the results with and without the non-linear term in the BK equation in order to study the impact of saturation effects on the measurable structure functions and nuclear modification factor. The difference of these results rises with decreasing Bjorken x and increasing scale. These predictions are of interest to the physics program at the future ep and eA colliders.
