The Ciafaloni-Catani-Fiorani-Marchesini (CCFM) evolution equation
extended with a quadratic term taken from the Balitsky–Kovchegov (BK)
equation combines both coherence and saturation physics. The solution of
the hard emissions approximation of this equation (called KGBJS here) is
going to be presented in case of fixed and running coupling constant.
The new solutions are going to be compared to gluon densities resulting
from the CCFM and BK equations. Implications for the saturation scale
behavior are going to be discussed. We also discuss a solution of KGBJS
written directly for momentum gluon density.
