Working Group 3

  • Topic 1 : Survey of the exsisting/missing models.
  • Topic 2 : Application of the Les Houches validation scheme. We would like to perform a 4 star comparison between FR and LH for the following models:
    • I. MSSM full validation.
      • Description: validation of cMSSM with LH+CH, FR+WO and the WO,SH stock versions.
      • Names: Benj, Sasha, Steffen, Christian.
      • Status: Several processes have discrepancies. Sasha is looking into the CH files. Here is an example
      • To-do: get final agreeement.
    • II. Randall-Sundrum.
      • Description: validation of RS between MG-stock, FR+CH, FR+WO.
      • Names: Neil, Sasha, Priscila, Christian.
      • Status: All model files available. Next step is comparison with MG-stock implementation of RS by Priscila and Qiang in v4. Finally, validation with FR+MG5 will be done.
      • To-do: get final agreeement.
    • III. Walking Technicolor.
      • Description: validation of WT FR vs LH versions with CalcHEP and MG and more...
      • Names: Sasha, Fabio, Claude.
      • Status: To be started. FR version to be validated with the LH version in CH. Paper SB, and Francesco Sannino (arXiv:0809.0793 [hep-ph]).
      • To-do: get final agreeement.
    • IV. Little Higgs with T-parity.
      • Description: validation of LHwT FR vs LH versions with CalcHEP and MG and more..
      • Names: Fabio, Sasha, Celine, Claude, Christian.
      • Status: To be started. The LanHEP sources are available by Sasha. Here is the CalcHEP implementation: http://hep.pa.msu.edu/LHT/lht.zip An implementation is also available in WHIZARD.
      • To-do: get final agreeement.
    • V. Lepto-Quarks.
      • Description: validation of LHwT FR vs LH versions with CalcHEP and MG and more..
      • Names: Fabio, Sasha, Claude, Christian.
      • Status: To be started. Lepto-Quarks : FR version to be validated with the LH version in CH. hep-ph/0502067.To validate this model we need a FR implementation of the Lagrangian in the paper above and its export into, let's say, MG5. Complete version of the CH implementation(including SU(3)xSU(2)xU(1)) is ready and will be available. model files.
      • To-do: get final agreeement.
    • VI. Background field method.
      • Description: Implementation of the background field method model and comparison with the usual approach in the SM.
      • Names: Fabio, Benj, Celine.
      • Status: Fermion, gauge and Higgs sector implemented.
      • To-do: Ghosts to be fixed, validation to be done (vs. FeynArts).
