Positronium energy levels at order m α7: vacuum polarization corrections in the two-photon-annihilation channel
Abstract
We have calculated all contributions to the energy levels of parapositronium at order m α7 coming from vacuum polarization corrections to processes involving virtual annihilation to two photons. This work is motivated by ongoing efforts to improve the experimental determination of the positronium ground-state hyperfine splitting.
