Abstract
The single photon annihilation contributions for the positronium ground state hyperfine splitting are calculated analytically to order using NRQED. Based on intuitive physical arguments the same result can also be determined by a trivial calculation using results from existing literature. Our result completes the hyperfine splitting calculation to order . We compare the theoretical prediction with the most recent experimental measurement.
