Gravitational wave signatures from domain wall and strong first-order phase transitions in a two complex scalar extension of the Standard Model
Abstract We consider a simple extension of Standard Model by adding two complex singlet scalars with a U(1) symmetry. A discrete Z 2 × Z 2 ′ $$ {\mathcal{Z}}_2\times {\mathcal{Z}}_2^{\prime } $$ symmetry is imposed in the model and the added scalars acquire a non zero vacuum expectation value (VEV)...
