Determination of electroweak parameters in polarised deep-inelastic scattering at HERA

The analysis performed here uses not only HERA- I data sets as in [6], but also the data sets obtained by HERA-II(including 2003 −2005 data) which has polarized electron and

Using parton densities derived from inclusive DIS cross sections, perturbative QCD calculations in NLO are found to give a consistent description of both the neutral and charged

In summary, the inclusion of the new cross section data from HERA-2 with polarised electron and positron beams lead to a substantial improvement of the precision on the weak

For the CC and NC cross sections, two main schemes are used : the On Mass Shell scheme (OMS) which uses the weak boson masses as fundamental parameters, and the Modified On Mass
