Abstract: The knowledge of the Higgs potential is crucial for understanding the origin of mass and the thermal history of our Universe. In this talk, we demonstrate how collider measurements, observations of stochastic gravitational wave signals, and microlensing experiments can complement each other to explore the multifaceted scalar potential. This will be illustrated using two theoretical frameworks: xSM and 2HDM. In 2HDM, we examine key ingredients triggering first-order phase transition by looking at the shape of the Higgs potential. In addition, I will discuss Primordial black hole formation due to late vacuum decay during the first-order phase transition and investigate this possibility at the electroweak scale in the xSM model. Furthermore, using the complex incarnation of the 2HDM, we will discuss the impact of the tunneling profile in the calculation of the baryon asymmetry associated with electroweak baryogenesis.
