英文摘要: In this paper, we utilize Nambu-Jona-Lasinio (NJL) mechanism to discuss the dynamical symmetry breaking for Weinberg-Salam model. In the NJL mechanism the symmetry breaking not only is determined by the potential of scalar field V(phi) but also has important relation with condensate of the fermion pair [<(psi)over bar>psi]. We find that the coefficient of quadric term of scalar field mu(2) greater than or equal to 0 can still cause symmetry breaking by Virtue of (<(psi)over bar>psi) not equal 0, and the vacuum expected value of scalar field obeys (phi) = (<(psi)over bar>psi), i.e., the order parameter which causes phase transition is the condensate of fermion pair (<(psi)over bar>psi). We also discuss the restoration problem of SU(2) x U(1) gauge symmetry breaking by the NJL mechanism at high temperatures.
