It is proposed to compute matrix elements for the (unphysical) K0p? ?p? transition to determine
the next-to-leading order low energy constants of the weak chiral Lagrangian. This allows
us to evaluate K ?(pp )I=0 decay amplitudes at this level of precision. This approach has several
significant advantages over the use of K ?pp transitions, most notably the elimination of
s-channel disconnected diagrams and the use of fewer inversions
