This software uses the electron self-energy correction as a demo, and the output of the calculation can be seen in reports/report.pdf.
Program that takes the integrals from QFT scattering amplitudes and simplifies them with some funny tricks. Currently supports only QED. WIP
Steps:
- Write out the amplitude, using regularized vertices and propagators.
- Use Feynman's trick to write all denominators as integrals.
- Perform integrals over four-momenta.
- Take highest order (in the cutoff momenta).
- Evaluate spin matrices.
