On Symmetry Restoration at Finite Temperature (Scalar Case)

Abstract

We investigate the effective potential for a scalar ${\Phi }^4$ 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.
