Abstract

We calculate the binding energy and structure of the positronium system in a light-front nonperturbative approach. The input interaction is from Quantum Electrodynamics first principles and one dynamical photon is explicitly included in the basis. We obtain the low-lying mass spectrum, which is found to be consistent with that from nonrelativistic quantum mechanics. Various excitation modes of the low-lying states can be identified from the associated wave functions. The photon distribution in the longitudinal direction is calculated for the low-lying positronium states.
