Kaon Weak Matrix Elements in 2+1 flavor DWF QCD: Renormalization and physical values

Presenter: Shu Li — Columbia University

Shu Li (for the RBC and UKQCD Collaborations)

We continue the presentation of the analysis of kaon weak matrix elements, measured on 2+1 flavor domain-wall fermion lattices, with the Iwasaki gauge action at β=2.13 and lattice size 243 64. We present the non-perturbative renormalization of the Δ S = 1 operators. After this renormalization, we discuss the physical values for the chiral perturbation theory constants we have determined and physical values for the matrix elements.
