Query: B_K in the chiral limit within the 1/Nc expansion   I report on a recent calculation done in collaboration with E. de Rafael
(hep-ph/0006146 v3) of the invariant B_K factor of K-Kbar mixing in the chiral
limit and to next-to- leading order in the 1/Nc expansion. This calculation is,
to the best of our knowledge, the first example of a calculation of B_K in
which there is an explicit analytic cancellation of the mu renormalization
scale and the scheme dependence between the Wilson coefficient and the
corresponding kaon matrix element. I try to emphasize the ideas involved in the
approach and how the method could be applied to other physical situations,
rather than the details of the numerical analysis for which I refer the reader
to the above reference.
