| Abstract | Measurements by the H1 and ZEUS collaborations of the neutral current cross sections
of deep inelastic polarised electron and positron-proton scattering are combined in
order to investigate the interference of weak and electromagnetic interactions at
high four-momentum transfer squared, Q2. The data provide the most accurate
measurements of the interference structure function xF3^{gamma Z}, which is
sensitive to the valence quark distributions down to lower values of Bjorken x.
The data on polarised cross section asymmetries, A^{\pm}, lead to the first
observation of parity violation in neutral current e^{\pm} p scattering
at distances down to 10^{-18} m. |
