- Abstract
- <jats:title>A<jats:sc>bstract</jats:sc> </jats:title><jats:p>Two-loop electroweak corrections to polarized Møller scattering are studied in two different schemes at low energies. We find the finite <jats:italic>Q</jats:italic><jats:sup>2</jats:sup> corrections to be well under control. The hadronic and perturbative QCD corrections to the <jats:italic>γZ</jats:italic> two-point function are incorporated through the weak mixing angle at low energies, which introduce an error of 0<jats:italic>.</jats:italic>08 <jats:italic>×</jats:italic> 10<jats:sup><jats:italic>−</jats:italic>3</jats:sup> in the weak charge of the electron <jats:inline-formula><jats:alternatives><jats:tex-math>$$ {Q}_W^e $$</jats:tex-math><mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msubsup> <mml:mi>Q</mml:mi> <mml:mi>W</mml:mi> <mml:mi>e</mml:mi> </mml:msubsup> </mml:math></jats:alternatives></jats:inline-formula>.
