Abstract

The effective potential of λϕ⁴₁₊₃ model with both sign of parameter m² is evaluated at T=0 by means of a simple but effective method for regularization and renormalization. Then at T≠ 0, the effective potential is evaluated in imaginary time Green Function approach, using the Plana formula. A critical temperature for restoration of symmetry breaking in the standard model of particle physics is estimated to be T_c≃ 510 GeV.
