摘要：

We present data for the scaling behavior of lattice QCD with two flavors of light Wilson fermions. This is done by matching pi n and rho masses at the two lattice sizes of 16(3) x 32 and 8(3) x 16. We find that at beta = 6/g(2) drop 5.3 the matching does not occur over a range extending down to beta = 3.5. For beta = 5.5 matching may be achieved at beta = 4.8 - 4.9, leading to a Delta beta = 0.6 - 0.7 which is higher than the perturbative 2-loop value of 0.45. In both cases we conclude that the simulations are very far from the perturbative scaling region.
