Positronium energy levels at order : Product contributions in the two-photon-annihilation channel
Gregory S. Adkins, Lam M. Tran, Ruihan Wang
Ongoing improvements in the measurement of positronium transition intervals motivate the calculation of the corrections to these intervals. In this work we focus on corr…
Positronium energy levels at order : 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 coming from vacuum polarization corrections to processes involving virtual annihilatio…
Positronium energy levels at order : light-by-light scattering in the two-photon-annihilation channel
Gregory S. Adkins, Christian Parsons, M. D. Salinger +2
Recent and ongoing experimental work on the positronium spectrum motivates new efforts to calculate positronium energy levels at the level of three loop corrections. We have obtain…
