Azimuthal asymmetries in deep inelastic scattering at HERA

摘要

The distribution of the azimuthal angle of charged and neutral hadrons has been studied in the hadronic centre-of-mass system for neutral current deep inelastic ep scattering with the ZEUS detector at HERA using an integrated luminosity of 45.21 pb–1. Measurements of the dependence of the moments of the azimuthal distribution on the pseudorapidity and minimum transverse energy of the final state hadrons are presented using the energy flow method.
