Electroweak phase transition in a model with gauged lepton number

Understand

In this work we study the electroweak phase transition in a model with gauged lepton number.

• Here, a family of vector-like leptons is required in order to cancel the gauge anomalies.
• Furthermore, these leptons can play an important role in the transition process.
• We find that this framework is able to provide a strong transition, but only for a very limited number of cases.
