Electroweak radiative corrections to polarized Mo/ller scattering asymmetries

One loop electroweak radiative corrections to left-right parity-violating Mo/ller scattering (${\mathit{e}}^{\mathrm{-}}$ ${\mathit{e}}^{\mathrm{-}}$→${\mathit{e}}^{\mathrm{-}}$ ${\mathit{e}}^{\mathrm{-}}$) asymmetries are presented. They reduce the standard model (tree level) prediction by 40±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 ${\sin }^2$ ${\mathrm{\theta }}_{\mathit{W}}$(${\mathit{q}}^2$) 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. © 1996 The American Physical Society.
