Kaon B-parameter with NF=2 dynamical Wilson fermions
F. Mescia, V. Gimenez, V. Lubicz +3
We present a preliminary study of the neutral kaon mixing bag parameter BK using two flavors of dynamical Wilson fermions. We determine the matrix element of the relevant DeltaS=2…

Renormalization Constants of Quark Operators for the Non-Perturbatively Improved Wilson Action
D. Becirevic, V. Gimenez, V. Lubicz +3
We present the results of an extensive lattice calculation of the renormalization constants of bilinear and four-quark operators for the non-perturbatively O(a)-improved Wilson act…

Non perturbative renormalization in coordinate space
V. Gimenez, L. Giusti, S. Guerriero +6
We present an exploratory study of a gauge-invariant non-perturbative renormalization technique. The renormalization conditions are imposed on correlation functions of composite op…
