    Abstract

    We have determined the asymptotic freedom Λ parameter by Monte Carlo simulations in an SU(2) lattice gauge theory with an action mixture of the fundamental and the spin 3 2 representations. The value obtained is Λ 3 2 = (0.0015 ± 0.0002) σ. The weak coupling prediction for the ratio with the Λ-Manton is also presented. We obtain a qualitative and quantitative agreement with this theoretical prediction. © 1984.
