Impact parameter dependence of the collinearly improved Balitsky-Kovchegov evolution equation / Matas, Marek (Prague, Tech. U.) ; Bendova, Dagmar (Prague, Tech. U.) ; Cepila, Jan (Prague, Tech. U.) ; Contreras, Jesus Guillermo (Prague, Tech. U.)
We have solved the Balistky-Kovchegov evolution equation including the impact-parameter dependence and obtained solutions which are not spoiled by theemergence of non-perturbative effects, dubbed Coulomb tails. [...]
