Combined QCD and electroweak analysis of HERA data — •Volodymyr Myronenko — DESY, Hamburg, Germany

A simultaneous fit of PDFs and electroweak parameters to HERA deep inelastic scattering data is presented. The input data are the neutral current, NC, and charged current, CC, inclusive cross sections that were previously used in the QCD analysis providing the HERAPDF2.0 PDFs. The NLO QCD plus LO electroweak analysis uses information on polarisation of the electron beam for the ZEUS data taken between 2004 and 2007. Results on the vector and axial-vector couplings of the Z boson to u- and d-type quarks, on the value of the electroweak mixing angle and the mass of the W boson are presented. The values obtained for the electroweak parameters are in agreement with Standard Model predictions.
