The analysis presented in this thesis concerns the e+p deep inelastic
charged current scattering cross sections measured with the H1 detector at HERA.
The analysed data were taken in the years 2003-04 at a centre-of-mass energy
s=319GeV and comprise two periods of
positron beams with positive and negative longitudinal polarisation, corresponding
to an integrated luminosity of 26.9 pb−1 and 20.7 pb−1, respectively.
The cross sections are measured in a kinematic region of
four-momentum transfer squared Q2⩾300GeV2 and inelasticity
y⩽0.9. \\
From the analysed data the polarisation dependence of the total charged current
cross section is determined for the first time at high Q2. The results are
compared with predictions of the Standard Model and found to be in agreement,
i.e. possible contributions from non-standard right-handed currents are
consistent with zero
