Description of the model
This is a simplified model for dark matter with a CP-even spin-0 mediator exchanged in the s-channel. Dark matter is taken to be a Dirac Fermion. For more details:

Model files

  • S2HDM.fr: main model file for spin-0 mediators.
  • cabibbo.rst, Massless4f.rst, Massless5f.rst: restriction files.
  • S2HDM.nb: this is an example Mathematica notebook that loads the model, checks consistency, calculates the Feynman rules and outputs the model in various formats.
  • unitarity.m: additional mathematica file loaded by the mathematica notebook, that checks unitarity, perturbativity and stability of potential
  • S2HDM_X.nlo files: NLOCT output, necessary to generate NLO UFO
