摘要:
We analytically solve the Sudakov suppressed Balitsky-Kovchegov evolution equation with fixed and running coupling constants in the saturation region. The analytic solution of the S-matrix shows that the exp(−O(η2)) rapidity dependence of the solution with the fixed coupling constant is replaced by the exp(−O(η3/2)) dependence in the smallest dipole running coupling case, as opposed to obeying the law found in our previous publication, where all the solutions of the next-to-leading order evolution equations comply with exp(−O(η)) rapidity...
