Title Scattering Amplitudes for Monopoles and the Pairwise Helicities
Abstract After a brief review of the challenges of calculating scattering amplitudes for electric and magnetic charges, as well as a discussion of Wigner’s “little group” and the helicity amplitude approach, I will discuss how S-matrix calculations can be extended to include magnetic charges. The answer involves an extension of the concept of helicity to a "pairwise helicity" involving two particles.
