theorydas / self-interacting-feynman

Code that produces Feynman diagrams of self-interacting fields of n-theory in N-body scatters up to arbitrary order.

Self Interacting Feynman Diagrams of n-th order

SIF(n) or Self Interacting Feynmans of n-th order is a Python program that calculates any possible Feynman Diagrams for a $n_1 \rightarrow n_2$ particle scattering for any n-theory self interacting field at any order of approximation.

Usage

To get a list of encoded information on Feynman Diagrams use the CreateFeynmanDiagrams() function.

For example:

The Feynman Diagrams of a 4-theory $2 \rightarrow n_2$ scattering up to a k_term order.

# Calculate the symbolic nodes for the Feynman Diagrams.
nodes = calculateFeynmanNodes(n_theory = 4, k_term = 2, ni = 2, nf = 2)

Todo

• The code currently only calculates the connection between the nodes of the Feynman diagrams in symbolic notation and does not draw the diagrams. This requires further suport.
• Separate illegal contributions where mediators are not connected to each end of the diagram.
