On the coupling constant bounds implying area decay of Wilson loop for   Z2 lattice gauge theories with Wilson action Boltzmann factor given by bond   variables described by transverse Ising model
  We obtain correlation functions for lattice gauge theories with action Boltzmann factor given by bond variables described by transverse Ising model and apply them to obtain area decay of the Wilson loop observable in a range of the coupling parameter larger than that obtained from mean field theory considerations.
