The real singlet extension of the Standard Model (RxSM) is implemented as a new model into BSMPT, following the convention of the Lagrangian in https://arxiv.org/abs/1512.05355 Eq. (11).

There are three (or four) input parameters for the model:

  • the quartic self-coupling of the singlet lambdaS,
  • the coupling between doublet and singlet lambdaHS,
  • the singlet VEV vS and, in case of vS == 0, additionally the singlet mass MassS.

The model is implemented for the case of the symmetric, i.e. unbroken, singlet phase vS == 0, and for the case of the broken singlet phase vS =/= 0. In the case of the unbroken phase, if the input parameter vS is set to zero, the input parameter MassS has to be provided. In the case of the broken phase, the input of MassS is ignored.

Thus, the input file has to contain four columns: lambdaS, lambdaHS, vS, MassS. An example input file is attached here.
