Positronium hydride decay into proton, electron, and one or zero photons

M. Jamil Aslam, Wen Chen, Andrzej Czarnecki +2

Decay rates of the positronium hydride PsH, a bound state of a proton, a positron, and two electrons, are determined for two rare channels, PsH $\to p^{+}{e}^{-}\gamma$ and PsH $\to p^+ e^-…
