Long-Distance 1/Nc Corrections to Density-Density Operators in K --> pi pi Decays
T. Hambye, P. Soldan
Abstract
In this talk we discuss the general method to calculate loop corrections to Delta S=1 density-density operators in the 1/Nc approach. As a result we present the long-distance evolution of the operators Q6 and Q8 to O(p0/Nc) in the chiral and the 1/Nc expansions.
