Description
In this talk a solution of the target-rapidity Balitsky-Kovchegov (BK) equation at the next-to-leading order (NLO) level is presented. At first, a version of the BK equation that includes only most important collinear part of the NLO contribution is used and the solution with the complete impact-parameter dependence is shown, including the orientation of the dipole with respect to the impact-parameter vector. This solution is used to compute the structure functions of the proton and the diffractive photo- and electro-production of vector mesons off protons. The predictions agree well with HERA and LHC data, confirming that the target-rapidity Balitsky-Kovchegov equation with the full impact-parameter dependence is a viable tool to study the small Bjorken-$x$ limit of perturbative QCD at current facilities like RHIC and LHC as well as in future colliders like the EIC.
Furthermore, a version of the BK equation that includes the full NLO contribution is used and the solution with the dependence on magnitudes of the size of the dipole and of the impact parameter is shown.}
