Description
The knowledge of the Higgs potential is crucial for understanding the origin of mass and the thermal history of our Universe. We show how collider measurements and observations of stochastic gravitational wave signals can complement each other to explore the multiform scalar potential in 2HDM. Accounting for theoretical and current experimental constraints, we analyze the key indredients in the shape of the Higgs potential triggering the transmutation in phase transition, focusing on the barrier formation and the upliftment of the true vacuum. The strong phase transition regime is favored for lower scalar masses, rendering strong extra motivation for collider searches. We contrast the dominant colllider signals at the HL-LHC with observable gravitational wave signal at LISA. We obtain that the HL-LHC will be able to cover a vast range of the strong phase transition parameter space, with scalar decays to heavy fermions being the most promising smoking gun signatures.
