Electroweak radiative corrections to polarized Mo/ller scattering asymmetries

Abstract

One loop electroweak radiative corrections to left-right parity-violating Mo/ller scattering (${\mathit{e}}^{\mathrm{\ensuremath{-}}}$${\mathit{e}}^{\mathrm{\ensuremath{-}}}$\ensuremath{\rightarrow}${\mathit{e}}^{\mathrm{\ensuremath{-}}}$${\mathit{e}}^{\mathrm{\ensuremath{-}}}$) asymmetries are presented. They reduce the standard model (tree level) prediction by 40\ifmmode\pm\else\textpm\fi{}3% where the main shift and uncertainty stem from hadronic vacuum polarization loops. A similar reduction also occurs for the electron-electron atomic parity-violating interaction. That effect can be attributed to an increase of ${\mathrm{sin}}^{2}$${\mathrm{\ensuremath{\theta}}}_{\mathit{W}}$(${\mathit{q}}^{2}$) by 3% in running from ${\mathit{q}}^{2}$=${\mathit{m}}_{\mathit{Z}}^{2}$ to 0. The sensitivity of the asymmetry to ``new physics'' is also discussed. \textcopyright{} 1996 The American Physical Society.
