Electroweak Radiative Corrections To Polarized Møller Scattering Asymmetries

Abstract

One loop electroweak radiative corrections to left-right parity violating Møller scattering ($e^{-}{e}^{-}\to e^{-}{e}^{-}$) asymmetries are presented. They reduce the standard model (tree level) prediction by 40$\pm 3$ \% 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 ${\sin }^2{\theta }_W(q^2)$ by $3\%$ in running from $q^2=m_Z^2$ to 0. The sensitivity of the asymmetry to ``new physics'' is also discussed.
