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'. |
