Application of lattice methods to the investigation of Weinberg-Salam model


Lattice Weinberg-Salam model at zero temperature and for the realistic values of couplings is investigated numerically in quenched approximation (when the dynamical fermions are neglected). The region of the phase diagram that contains phase transition between the physical Higgs phase and the unphysical symmetric phase is considered. This is the region of the phase diagram, where continuum physics is approached within the lattice model.
