Re(A0), Re(A2) and RG evolution for Nf=3
Abstract
We present results of Re (A0) and Re (A2) calculated using HYP staggered fermions on the lattice of 163 × 64 at β=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=3. This subtlety is resolved by finding a finite solution to RG equation and the results are presented.
