Anomalous magnetic moment of the positronium ion
Yi Liang, Paul L. McGrath, Andrzej Czarnecki
We determine the gyromagnetic factor of the positronium ion, a three-body system consisting of two electrons and a positron, including first relativistic corrections. We find that…

Muon decay spin asymmetry
Fabrizio Caola, Andrzej Czarnecki, Yi Liang +2
We compute the spin asymmetry of the muon decay through O(alpha^2) in perturbative QED. These two-loop corrections are about a factor five (twenty) smaller than the current statist…
