Abstract

We show that positronium hyperfine splitting and Delbrück scattering impose stringent bounds on the coupling of a light neutral boson to the electron-positron and the photon field. These limits are relevant for the “new-particle interpretation” of coincident electron-positron lines observed at GSI.
