Recent progress in ε'/ε calculation using staggered fermions

Weonjong Lee, (LANL)

Abstract

Phenomenological importance of Nature's indirect CP violation is reviewed. I present a recent progress in calculating perturbative matching coefficients between the staggered fermion operators and the continuum operators, defined in the NDR scheme, especially for the indirect CP violation. I also report the recent progress in WI test and gauge invariance test for staggered fermion operators used in the numerical study of the ε'/ε calculation.
