= Working Group 1: development of new quantum field theory functionalities. =

  * I. '''Superfields'''.
      * ''Description'': implementation and development of superfields in !FeynRules.
      * ''Names'': __Benj__, Claude, Thomas.
      * ''Status'': Wess-Zumino is done.
      * ''To-do'': Vector superfield implementation is ongoing + rewriting of the MSSM + validation vs. !FeynArts.
     
  * II. '''Mass matrices'''.
      * ''Description'': addressing of the diagonalization of mass matrices. The main idea is to have FR to output a simple code that takes a LH file in and spits out LH file with the mass matrix diagonalized.
      * ''Names'':  __Martin__, Neil, Benj, David, Thomas, Olivier, Christian.
      * ''Status'':
      * ''To-do'':

  * III. '''Higher-dimensional operators'''.
      * ''Description'': Splitting higher dimensional operators or 4-point vertices into 3-point ones by introducing auxiliary fields.
      * ''Names'': Claude, Fabio, Christian, Sasha.
      * ''Status'': An iterative algorithm for reducing a n-point vertex to n-3 three-point vertices introducing n-3 charged auxiliary fields exists and can be proven easily; the applicability is limited by the necessity of transporting lorentz and spinor indices along the auxiliary lines, potentially leading to spin > 2 auxiliary fields.
      * ''To-do'': Implementation.

  * IV. '''FR Java Interface'''.
      * ''Description'': Java interface for introducing models (Neil) based on Gauge symmetries and particle content.
      * ''Names'': __Neil__, Christian
      * ''Status'': Neil has already an alpha version. 
      * ''To-do'': Claude suggests to have it staged. First thing is to produce the model file but not the lagrangian. 
 
  * V. '''Automatic Validation Package from the Web'''.
      * ''Description'': Instead of making the validation package based on the Mathematica Notebook + several MC's available to the users, a web interface is built to do this from the web.
      * ''Names'': __Neil__, Claude, Benj.
      * ''Status'': To do
      * ''To-do'': everything.
