Gravitational wave and collider implications of electroweak baryogenesis aided by non-standard cosmology

Understand

We consider various models realizing baryogenesis during the electroweak phase transition (EWBG).

• Our focus is their possible detection in future collider experiments and possible observation of gravitational waves emitted during the phase transition.
• We also discuss the possibility of a non-standard cosmological history which can facilitate EWBG.
• We show how acceptable parameter space can be extended due to such a modification and conclude that next generation precision experiments such as the ILC will be able to confirm or falsify many models realizing EWBG.
