T photons in deep inelastic scattering
First measurements of cross sections for isolated prompt photon production in deep inelastic ep scattering have been made using the ZEUS detector at the HERA electron-proton collider using an integrated luminosity of 121 pb. A signal for isolated photons in the transverse energy and rapidity ranges 5 < E T < 10GeV and −0.7 < η < 0.9 was observed for virtualities of the exchanged photon of Q > 3...
متن کاملIsolated photons in deep inelastic scattering.
Photon radiation at large transverse momenta at colliders is a detailed probe of hard interaction dynamics. The isolated photon production cross section in deep inelastic scattering was measured recently by the ZEUS experiment, and found to be considerably larger than theoretical predictions obtained with widely used event generators. To investigate this discrepancy, we perform a dedicated part...
متن کاملProduction of Isolated Photons in Deep Inelastic Scattering
We present here the predictions obtained from a calculation of the inclusive isolated photon production cross section in deep inelastic scattering. The results are compared with the cross section measurement of the ZEUS collaboration and found in good agreement with all aspects of it. Furthermore, a way of measuring the quark-to-photon fragmention function in DIS is also briefly outlined.
متن کاملLow-Energy Compton Scattering of Polarized Photons on Polarized Nucleons
The general structure of the cross section of γN scattering with polarized photon and/or nucleon in initial and/or final state is systematically described and exposed through invariant amplitudes. A low-energy expansion of the cross section up to and including the order O(ω4) is given which involves ten structure parameters of the nucleon (dipole, quadrupole, dispersion, and spin polarizabiliti...
متن کاملJets in Deep Inelastic Scattering and High Energy
Recent results on jet production in neutral current deep inelastic scattering and high energy photoproduction at the HERA electron-proton-collider are briefly reviewed. The results are compared to QCD expectations in NLO and αs determinations using these data are summarized.
