We present results from a numerical solution of the next-to-leading order (NLO) BalitskyKovchegov
(BK) equation in coordinate space in the large Nc limit. We show that the solution
is not stable for initial conditions that are close to those used in phenomenological applications
of the leading order equation. We identify the problematic terms in the NLO kernel as being
related to large logarithms of a small parent dipole size, and also show that rewriting the equation
in terms of the “conformal dipole” does not remove the problem. Our results qualitatively agree
with expectations based on the behavior of the linear NLO BFKL equation.
