Muon Loop Light-by-Light Contribution to Hyperfine Splitting in Muonium
arXiv:1402.5372 · doi:10.1103/PhysRevLett.112.173004
Abstract
Three-loop corrections to hyperfine splitting in muonium generated by the gauge invariant sets of diagrams with muon and tauon loop light-by-light scattering blocks are calculated. These results complete calculations of all light-by-light scattering contributions to hyperfine splitting in muonium.
