Description
The scaling behavior of pure gauge SU(3) in the region β=5.85-7.60 is examined by a Monte Carlo renormalization group analysis. The coupling shifts induced by factor 2 blocking are measured on both 324 and 164 lattices with high statistics. A systematic deviation from naive 2-loop scaling is clearly seen. The mean field and effective coupling constant schemes explain part, but not all, of the deviation. It can be accounted for by a suitable change of coupling constant, including a correction term O(g7) in the 2-loop lattice β function. Based on this improvement, √σ /ΛMbarSnf=0 is estimated to be 2.2±0.1 from the analysis of the string tension σ
