New measurement of charge asymmetry xF₃ from HERA
Schoeffel, Laurent
Original · EN
After presenting the recent measurements of neutral current cross section in DIS at HERA, we explain the effect of the γ-Z₀ interference at the electro-weak scale, visible on these data. Then, the beam charge difference xF₃ is measured and the interference itself is extracted. Results are discussed in the context of perturbative QCD.
