Collinearly improved impact-parameter dependent Balitsky-Kovchegov evolution
Original language description
The Balitsky-Kovchegov equation has been successfully used to describe a wide range ofprocesses in diffraction, saturation physics and many others. It has a wide use both inphenomenology and theory; its solution (the scattering amplitude) has receivedsignificant attention in the past years. However, solutions including the impact-parameter dependencehave been shown to exhibit so-called Coulomb tails, which spoil their use in phenomenology, due to an unphysical growth of the target. In this study weshow, that choosing the recently proposed collinearly improved kernel suppresses the effectof the Coulomb tails and enables us to describe simultaneously structure function dataas well as vector meson photoproduction.
