$Re(A_0)$, $Re(A_2)$ and RG evolution for $N_f=3$

High Energy Physics - Lattice 2008-11-26 v2

Abstract

We present results of Re(A0)Re (A_0) and Re(A2)Re (A_2) calculated using HYP staggered fermions on the lattice of 163×6416^3 \times 64 at β=6.0\beta=6.0. These results are obtained using leading order chiral perturbation in quenched QCD. Buras's original RG evolution matrix develops a removable singularity for Nf=3N_f=3. This subtlety is resolved by finding a finite solution to RG equation and the results are presented.
