epsilon'/epsilon in the 1/N_c Expansion
T. Hambye, P. H. Soldan
We present a new analysis of the ratio epsilon'/epsilon which measures the direct CP violation in K\toππdecays. We use the 1/N_c expansion within the framework of the effective chi…

A New Analysis of B_6^(1/2), B_8^(3/2), and the Delta I=1/2 Rule in the 1/N_c Expansion for K --> pi pi Decays
G. O. Koehler
We present a new calculation of long-distance contributions to the K --> pi pi amplitudes using the 1/N_c expansion within the framework of chiral perturbation theory. Along these…
