Wilsonian matching of effective field theory with underlying QCD - art. no. 014023

We propose a novel way of matching effective field theory with the underlyi ng QCD in the sense of a Wilsonian renormalization group equation (RGE). We derive Wilsonian matching conditions between current correlators obtained by the operator product expansion in QCD and those by the hidden local symm etry (HLS) model. This determines without much ambiguity the bare parameter s of the HLS at the cutoff scale in terms of the QCD parameters. Physical q uantities for the pi and rho system are calculated by the Wilsonian RGE's f rom the bare parameters in remarkable agreement with the experiment.
