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.
