Description

We use the running coupling Balitsky–Kovchegov (rcBK) equation to study the rapidity dependence of saturation in inclusive HERA data and we discuss the behaviour of it’s numerical solution. The rcBK equation has been solved using Runge–Kutta methods. The influence of the parameters implicit in the numerical evolution has been studied. They include, among others, the order of the Runge–Kutta evolution, the size of the different grids and the step in the numerical evolution. Some suggestions on the minimum value of these parameters are put forward. Also the dependence of the rcBK solution on the shape of initial conditions will be addressed.
