• lambda phi(4) model
• Higgs mass
• regularization renormalization method

Based on a new regularization-renormalization method, the lambda phi(4) model used in standard model (SM) is studied both perturbatively and nonperturbatively by Gaussian effective potential (GEP). The invariant property of two mass scales is stressed and the existence of a (Landau) pole is emphasized. Then after coupling with the SU(2) x U(1) gauge fields, the Higgs mass in standard model (SM) can be calculated to be m(H)approximate to 138 GeV. The critical temperature (T-c) for restoration of symmetry of Higgs field, the critical energy scale (mu(c), the maximum energy scale under which the lower excitation sector of the GEP is valid) and the maximum energy scale (mu(
