Title: Gravitational wave, collider and dark matter signals from a scalar singlet electroweak baryogenesis,
Abstract: We analyse a simple extension of the SM with just an additional scalar
singlet coupled to the Higgs boson. We discuss the possible probes for
electroweak baryogenesis in this model including collider searches,
gravitational wave and direct dark matter detection signals. We show that a
large portion of the model parameter space exists where the observation of
gravitational waves would allow detection while the indirect collider searches
would not.
