Electron and neutron electric dipole moment in the 3-3-1 model with heavy leptons

Understand

We calculate the electric dipole moment for the electron and neutron in the framework of the 3-3-1 model with heavy charged leptons.

• We assume that the only source of $CP$ violation arises from a complex trilinear coupling constant and the three complex vacuum expectation values.
• However, two of the vacua phases are absorbed and the other two are equal up to a minus sign.
• Hence only one physical phase survives.
