Abstract: (APS)
The β function of SU(3) lattice gauge theory with three flavors of light dynamical quarks is obtained numerically by use of the (improved) ratio method. It appears to have a dip structure similar to that found in the theory without quarks. Our data seem to suggest that deviations from asymptotic scaling may be small for β≳5.3.- GAUGE FIELD THEORY: SU(3)
