摘要 (Abstract):
We suggest an appealing strategy to probe a large class of scenarios beyond the Standard Model predicting first-order phase transitions (FOPT) in future gravitational-wave experiments. Our analysis deploys measurements from the gravitational waves channels and high energy particle colliders. We discuss this methodology focusing on two specific examples provided by well known extensions of the Standard Model that incorporate an additional electroweak-singlet scalar or an additional SU(2)_L triplet scalar coupled to the Higgs boson. We will show that a strong electroweak FOPT is naturally realised in both scenarios, one in consistency with the existence of dark matter and another one - with the recently measured anomaly in W boson mass. I will discuss how such scenarios could be potentially probed in future space-based interferometers such as LISA, DECIGO, BBO, TianQin, TAIJI projects and as well as in future colliders such as FCC, ILC, CEPC.
