Model Description

This model describes the minimal realisation of the Type III Seesaw. It is an extension of the SM where a fermionic triplet is add to the matter content. The fermionic triplet is introduced into the form of a heavy Dirac charged lepton tr+/- and a heavy Majorana neutral lepton tr0.

Model Files

  • [typeIIIseesaw1.0.fr]: this is the file containing the model
  • [typeIIIseesaw.nb]: this is a Mathematica notebook that loads the model and export it to the MadGraph? and CalcHep? format.

Validation

Notes

We implemented the couplings to Goldstone bosons so the implmentation allows for the use of Feynman gauge. We have checked that the exportation to the CalcHep? format is successfull however we did not check the CalcHep? output.
