| Abstract | Using the deep inelastic e+ p and e- p charged and neutral current scattering
cross sections, including data with polarised electron beams, a combined
electroweak and QCD analysis is performed to determine electroweak parameters
accounting for their correlation with parton distributions. The precision
has been improved in particular for u quark coupling to the Z boson
with respect to the published results based on the unpolarized HERA data only.
The determinations from HERA are compared with those from LEP and Tevatron. |
