The Measurement of Azimuthal Asymmetries In Deep Inelastic Scattering
The distribution of the azimuthal angle for the charged hadrons has been studied in the hadronic centreof-mass system for neutral current deep inelastic positron-proton scattering at HERA. Measurements of the dependence of the moments of this distribution on the transverse momenta of the charged hadrons are presented. Asymmetries that can be unambiguously attributed to perturbative QCD processe...

The distribution of the azimuthal angle for the charged hadrons has been studied in the hadronic centre-of-mass system for neutral current deep inelastic positron-proton scattering with the ZEUS detector at HERA.

متن کاملAsymmetries in Deep Inelastic Scattering
We review the existing data on asymmetries in deep inelastic muon scattering involving changes in the lepton and quark helicities. The status of the present E.M.C. experiment on spin structure functions is discussed together with future developments. The process of Deep Inelastic Scattering using electron, muon and neutrino probes has been very successful in developing our present understanding...
متن کاملAsymmetries in Deep Inelastic Scattering
We demonstrate that the angular distribution of hadrons produced in semiinclusive deep inelastic final states is related to the inclusive longitudinal structure function. This relation could provide a new method of accessing FL(x,Q 2) in deep inelastic scattering measurements. The internal structure of the proton as probed in deep inelastic lepton-proton scattering can be parameterised in terms...
متن کاملMeasurement of azimuthal asymmetries in neutral current deep inelastic scattering at HERA
The distribution of the azimuthal angle of charged and neutral hadrons relative to the lepton plane has been studied for neutral current deep inelastic ep scattering using an integrated luminosity of 45 pb taken with the ZEUS detector. The kinematic range is 100 < Q < 8000 GeV, 0.2 < y < 0.8 and 0.01 < x < 0.1 where Q is the virtuality of the exchanged boson, y is the inelasticity and x is the ...
