Description
First-order electroweak phase transition plays a central role in electroweak baryogenesis.
However, it is known that unwanted gauge dependence exists in critical temperature
and Higgs vacuum expectation value in an ordinary perturbative calculation scheme.
In this talk, we revisit the electroweak phase transition in the SM with a singlet scalar
utilizing a gauge-independent method proposed by Patel and Ramsey-Musolf
and make a comparison with previous results. Impact on deviation of triple Higgs coupling
from the standard model is also discussed.
