SFQED

Python package for calculating QED cross sections in a strong background magnetic field. Currently, the package includes the following processes:

• Synchrotron radiation
• One-photon pair creation
• One-photon pair annihilation
• Compton scattering
• Two-photon pair creation
• Two-photon pair annihilation

Tutorial

The file PlotsQEDAllProcesses.ipynb includes examples on how to use the package.
