چکیده
We investigate the effective potential for a scalar Φ 4 theory with spontaneous symmetry breaking at finite temperature. All 'daisy' and 'super daisy' diagrams are summed up and the properties of the corresponding gap eqation are investigated. It is shown exactly that the phase transition is first order.

We investigate the effective potential for a scalar Φ 4 theory with spontaneous symmetry breaking and finite temperature. All 'daisy' and 'super daisy' diagrams are summed up and the properties of the correspponding gap eqation are investigated. It is shown exactly that the phase transition is first order.

Existence and properties of the electroweak phase transition in the early universe depend strongly on the mass of the Higgs scalar M H. There is presumably no true symmetry restoration at high temperature. Nevertheless , a first order phase transition occurs in the standard model for M H ∼ < 70 GeV. For a realistic scalar mass M H ∼ > 70 GeV the transition to the high temperature regime is desc...

This paper continues a study of field theories specified for the nonuniform lattice in the finite-dimensional hypercube with the use of the earlier described deformation parameters. The paper is devoted to spontaneous breakdown and restoration of symmetry in simple quantum-field theories with scalar fields. It is demonstrated that an appropriate deformation opens up new possibilities for symmet...
