## Idea

The photon is the gauge boson of the electromagnetic field, hence of electromagnetic radiation and of light.

In quantum electrodynamics the photon interacts with the electron via the electron-photon interaction.

### Classification of long-range forces

Classification of possible long-range forces, hence of scattering processes of massless fields, by classification of suitably factorizing and decaying Poincaré-invariant S-matrices depending on particle spin, leading to uniqueness statements about Maxwell/photon-, Yang-Mills/gluon-, gravity/graviton- and supergravity/gravitino-interactions:
