Direct numerical solution of the coordinate space Balitsky-Kovchegov equation at next-to-leading order
Physical Review D
We present the first numerical solution to the next to leading order Balitsky-Kovchegov (BK) equation in coordinate space in the large-N_c limit. In addition to the dipole operator we also solve the evolution of the "conformal dipole" for which the conformal invariance breaking double logarithmic term is absent from the evolution equation. The NLO corrections are shown to slow down the evolution. We show that the solution depends strongly on the details of the initial condition, and that the
... ution to the equation is not positive definite with all initial conditions relevant for phenomenological applications.
