On Nambu Monopole Dynamics in the SU(2) Lattice Higgs Model
  It is shown that the SU(2) Higgs model on a lattice is equivalent to the Georgi--Glashow model in the limit of a small coupling constant between the Higgs and gauge fields. It can therefore be concluded that the transition between the confinement and symmetric phases in the 3+1 dimensional SU(2) Higgs model at finite temperature is accompanied by condensation of Nambu monopoles.
