Abstract

We consider the next level of corrections to the

e^{+} e^{-} \to μ^{+} μ^{-}

charge asymmetry for beam energies presently of interest. If we define these weak single-loop corrections with an on-mass-shell renormalization scheme, only the

Z

-boson self-energy is nonnegligible and that contribution itself can be redefined into the Born term upon change of scheme to an expansion in the Fermi coupling constant. A compact formula for the

γ Z

box diagram is also presented.
