### Abstract:

As a minimal extension to the standard model, the electroweak group [iopmath latex="$SU(2)\otimes U(1)\otimes U'(1)$"] SU(2)U(1)U'(1) [/iopmath] is considered to examine the possibility of an electroweak phase transition. The extended symmetry is broken by the doublet Higgs and isospin singlet bosons. An effective potential is proposed which makes the [iopmath latex="$Z'$"] Z' [/iopmath] boson enter into the standard model scenario due to radiative correction. Constraints on the masses of the [iopmath latex="$Z'$"] Z' [/iopmath] and Higgs boson due to perturbative expansion at zero and finite temperature as well as loop expansion are calculated. There is a strong first-order electroweak phase transition at [iopmath latex="$T_c$"] Tc [/iopmath] around 125 GeV for reasonable mass values of the Higgs and [iopmath latex="$Z'$"] Z' [/iopmath] boson.
