Polarisation Dependence of the Total CC e±p Cross Section.

Data taken with the H1 detector, with longitudinally polarised electrons and positrons in collision with unpolarised protons at HERA, are used to measure the charged current cross section σCCtot for Q2 > 400 GeV2 and inelasticity y < 0.9. The polarisation dependence of the measured cross section is in agreement with the Standard Model predictions. © 2005 American Institute of Physics [ABSTRACT FROM AUTHOR]
