| Title | Parity-Violating Inelastic Electron-Proton Scattering at Low $Q^2$ Above the Resonance Region | ||||
| Abstract | The parity-violating asymmetry was measured for the inelastic scattering of electrons from the proton, at $Q^2 = 0.082$~GeV$^2$ and $ W = 2.23$~GeV, above the resonance region. The result $A_{\rm inel} = - 13.5 \pm 2.0 ({\rm stat}) \pm 3.9 ({\rm syst})$~ppm is in agreement with theoretical calculations, and helps to validate the modeling of the $\gamma Z$ interference structure functions $F_1^{\gamma Z}$ and $F_2^{\gamma Z}$ used in those calculations, which are also used for determination of the $\Box_{\gamma Z}$ contribution to parity-violating elastic scattering measurements. A positive parity-violating asymmetry for inclusive $\pi^-$ production was observed, as well as positive beam-normal single spin asymmetry for scattered electrons and a negative beam-normal single spin asymmetry for inclusive $\pi^-$ production. | ||||
