Working Group 1 / Working Group 2 / Working Group 3 / Working Group 4

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: FeynRules sytax for declaring mixing matrices is fixed and understood by FeynRules.
    • To-do: Code generation for the model calculator, interfacing with Diag package by Thomas.
  • 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. 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.
