Electroweak results from HERA
  The inclusive neutral and charged current deep inelastic scattering processes at high Q2 provide the main basis for electroweak studies at HERA. These studies include the determination of the W boson propagator mass and weak neutral current couplings of light quarks to the Z0 boson. The polarised electron or positron beam at HERA II gives rise to additional sensitivities for these studies. Exceptions also exist; this is the case for the single W production.
