 * '''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__, Claude, Thomas.
      * ''Status'': Wess-Zumino is done.
      * ''To-do'': Vector superfield implementation is ongoing + rewriting of the MSSM.

 First thing is to get agreement between the LH SUSY implementation in CH and all the others as in the big FR paper (Sasha for LH/CH and Steffen for Sherpa).

    * Randall Sundrum (started at the workshop) : FR and LH implementations will be validated in CalcHEP (3 star) and in WHIZARD (4 star): Priscila, Neil, Sasha, Christian. 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.

    * Walking Technicolor : FR version to be validated with the LH version in CH. Paper SB, and Francesco Sannino (arXiv:0809.0793 [hep-ph]). 

    * Little Higgs with T-parity. 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.

    * 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. [attachment:LeptoQuarks.tgz]
