Description
We analytically solve the full next-to-leading logarithmic Balitsky-Kovchegov equation 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 linear
rapidity decrease with rapidity of the exponent in running coupling case is replaced by rapidity
raised to power of 3/2 decreasing. The collinearly-improved Balitsky-Kovchegov equation are also
analytically solved in the saturation regime. It shows that the double collinear logarithms do not
contribute to the S-matrix and the solution is the same as the one obtained from the leading order
Balitsky-Kovchegov equation. The numerical solutions to the leading order and full next-to-leading
logarithmic Balitsky-Kovchegov equations are performed in order to test the analytic results derived
in the saturation regime.
