First-order electroweak phase transition in a complex singlet model with ℤ3 symmetry

First-order electroweak phase transition in a complex singlet model with ℤ3 symmetry

Abstract We consider an extension of the Standard Model with a complex singlet scalar, where a global U(1) symmetry is explicitly broken to ℤ3 symmetry. We study the two-step electroweak phase transition in the model and find that it can be of first-order if the heavy scalar mass falls in the range...
