Three-photon-annihilation contributions to positronium energies at order $m α^{7}$

Gregory S. Adkins, Minji Kim, Christian Parsons +1

Positronium spectroscopy (n=1 hyperfine splitting, n=2 fine structure, and the 1S-2S interval) has reached a precision of order 1 MHz. Vigorous ongoing efforts to improve the exper…

Positronium energy levels at order $m α^{7}$ : vacuum polarization corrections in the two-photon-annihilation channel

Gregory S. Adkins, Christian Parsons, M. D. Salinger +1

We have calculated all contributions to the energy levels of parapositronium at order $m α^{7}$ coming from vacuum polarization corrections to processes involving virtual annihilatio…
