Phase transition in multi-scalar-singlet extensions of the Standard Model

We propose a generalization of the Standard Model (SM) by adding two real gauge-singlets S1, S2. The field S1 will improve the strength of the electroweak phase transition (EWPT). Imposing a Z2 symmetry on the field S2 makes this field a possible candidate for dark matter. Both singlets interact wit...
