Gravitational waves from phase transition in split NMSSM

11 Dec 2018  ·  Demidov S. V., Gorbunov D. S., Kirpichnikov D. V. ·

We discuss gravitational wave signal from the strongly first order electroweak phase transition in the split NMSSM. We find that for sets of parameters predicting successful electroweak baryogenesis the gravitational wave signal can be within the reach of future experiments LISA, BBO and Ultimate DECIGO.
