摘要：

The electroweak phase transition (EWPT) is an important topic, it connects the Higgs physics with the evolution in the early universe. If it is strong 1st order, it can provide the environment for successful baryogenesis, and produce the observable gravitational wave signals. In this talk, I will briefly introduce my recent works on supercooled EWPT. In the first part, I will discuss the possible challenges when we want to explain the possible GW signal from PTA observations using supercooled EWPT. Then in the second part, I will discuss the case where PBH can be produced during a supercooled EWPT, and discuss relevant phenomenology.
