FriedYennie gauge recalculation of the electron line induced radiativerecoil corrections to muonium hyperfine splitting
Abstract
A new analytic calculation of radiativerecoil corrections to muonium groundstate hyperfine splitting induced by electron line insertions is performed. The starting point of this calculation is presented by the FriedYennie gauge expression for the electron line factor. The final result confirms the one obtained previously from the apparently different expression in the Feynman gauge and removes the slight discrepancy which existed in the literature between the calculations in different gauges.
