0 A ug 2 00 6 Z 6 symmetry , electroweak transition , and magnetic monopoles at high temperature

We consider the lattice realization of the Standard Model with an additional Z6 symmetry. Numerical simulations were performed on the asymmetric lattice, which corresponds to the finite temperature theory. Our choice of parameters corresponds to large Higgs masses (MH > 90 Gev). The phase diagram was investigated and has been found to be different from that… CONTINUE READING
