DESCRIPTION:We consider a non-perturbative formulation of an SU(2) massive
  gauge theory on a space-time lattice\, which is also a discretised gauged
  non-linear chiral model. The lattice model is shown to have an exactly co
 nserved global SU(2) symmetry. If a scaling region for the lattice model e
 xists and the lightest degrees of freedom are spin one vector particles wi
 th the same quantum numbers as the conserved current\, we argue that the m
 ost general effective theory describing their low-energy dynamics must be 
 a massive gauge theory. We present results of a exploratory numerical simu
 lation of the model and find indications for the presence of a scaling reg
 ion where both a triplet vector and a scalar remain light.\n\nhttps://indi
