摘要:
We analytically solve the next-to-leading logarithmic Balitsky-Kovchegov equation approximated in the saturation regime, which includes corrections from quark and gluon loops, and large double transverse logarithms. The analytic result for the S-matrix in the saturation regime shows that the exp(−O(Y)) rapidity dependence of the running-coupling solution is replaced by exp(−O(Y3/2)) in the next-to-leading logarithmic solution. The collinearly improved Balitsky-Kovchegov equations are also analytically solved in the saturation regime. This sho...
