Front form QED(3+1): The spin-multiplet structure of the positronium spectrum at strong coupling
U. Trittmann (MPI Kernphysik, Heidelberg, Germany)🇩🇪
Abstract
Numerical results on the positronium spectrum in the front form of QED at large coupling constant are presented. Emphasis is put on the question whether one can derive an effective interaction at all, and whether this effective interaction is rotationally invariant. (Proceedings of Les Houches 1997)
