| Abstract |
Data taken with electrons and positrons of different longitudinal polarisation
states in collision with unpolarised protons at HERA are used to measure the
cross sections of the neutral current process, e^\pm p o e^\pm X.
The polarisation asymmetry is measured as a function of Q^2, the negative
four-momentum transfer squared, and compared with the Standard Model
prediction. An improved determination of xF_3 structure function is obtained
using the new data in combination with previously published unpolarised data
from HERA-I. |
