Lattice matrix elements confronting the experimental value of epsilon '/epsilon

A new lattice estimate of K --> 2 pi transitions claims, contrary to all ot her computations, that the hadronic matrix element for the gluon penguin op erator Q(6) has opposite sign and, in addition, is much larger than the vac uum saturation approximation. We comment under what conditions (if any) it is possible to reconcile this lattice result with the experimental value of epsilon'/epsilon. The dramatic impact of new physics in the kaon system th at seems to be required is not easily accommodated within our present theor etical understanding.
