TL;DR
This paper explores the potential for gravitational wave signals generated by a first-order electroweak phase transition in the split NMSSM, which could be detected by future space-based observatories.
Contribution
It demonstrates that certain parameter sets in the split NMSSM can produce detectable gravitational waves linked to electroweak baryogenesis.
Findings
Gravitational wave signals are within reach of future detectors like LISA, BBO, and DECIGO.
Parameter sets compatible with successful electroweak baryogenesis produce observable signals.
The study links particle physics models with gravitational wave phenomenology.
Abstract
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.
