= 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'': __Claude__, Neil, Benj. * ''Status'': To do * ''To-do'': everything.
