We study a theory less explored in the literature, that of a massive abeliangauge boson interacting with a massless fermion. In this framework we calculatethe electromagnetic potentials created by a point like massless charge. Wedetermine also the radiation associated with a change in the momentum of thecharge in the low energy regime. The results show both similarities anddiscrepancies with respect to quantum electrodynamics.
