N2 - We present the result for the invariant B(K) factor of K0-K̄0 mixing in the chiral limit and to next-to-leading order in the 1/N(c) expansion. We explicitly demonstrate the cancellation of the renormalization scale and scheme dependences between short- and long-distance contributions in the final expression. Numerical estimates are then given, by taking into account increasingly refined short- and long-distance constraints of the underlying QCD Green's function which governs the B(K) factor.
