Description
Phenomenological consequences of the strong first-order electroweak phase transition are discussed in an extension of the standard model with an inert doublet and vector-like leptons motivated by dark matter and the muon g−2 anomaly. We point out that a condition for the strong first-order electroweak phase transition inevitably induces a large logarithmic enhancement in Z boson decays, which relegates the explanation of the anomalous muon g-2 at below 2 sigma level. Future tests of the scenario are also discussed.
