Nonleptonic Kaon Decays from Lattice QCD

Speaker: Norman Christ

Improved methods and increased computer capabilities now allow direct calculation of the decay of the kaon into two pions to be carried out using lattice QCD.  Recent results for the complex, I=2, K -> pipi amplitude A_2 with physical kinematics will be presented.  Initial studies of the more difficult I=0 amplitude A_0 will also be described.  These studies give insight into the Delta I=1/2 rule and, when combined with new methods that will also be discussed, lay the foundation for an accurate calculation of the direct CP violating parameter epsilon'.
