Abstract

We report a calculation of the

m α^{6} \ln α^{- 1}

contributions to the triplet-singlet splitting of the positronium ground state. Our result,

Δ ν (α^{6} \ln α^{- 1}) = \frac{1}{2} m α^{6} \ln α^{- 1} = 46 MHz,

shifts the theoretical prediction from two standard deviations below to two standard deviations above the most recent experimental value.
