| Abstract |
Data taken with the H1 detector, for longitudinally polarised positrons in left and right handed states in collision with unpolarised protons at HERA, are used to measure the total charged current cross section for Q^2 >400 GeV^2 and inelasticity y < 0.9. The polarisation dependence of the total charged current cross section is compared with Standard Model expectations. The data are used to obtain an extrapolated total charged current cross section for a fully left handed positron beam. This extrapolation is found to be consistent with the expectations of the Standard Model. |
