Abstract
In the scattering of two electric charges, the particles acquire a shift in their net boostlike angular momentum, balanced by an opposite field contribution. This electromagnetic scoot effect appears at first order in post-Minkowskian expansion when conservation laws are evaluated on constant-time slices but disappears at this order on hyperboloidal slices. Here, we extend this analysis to scattering involving both electric and magnetic charges and compare the results with the purely electric case in the context of multiparticle state representations.
