Real and Virtual Photon Structure at Hera
نویسنده
چکیده
The structure of real and virtual photons has been studied in ep collisions at HERA using dijet production. Measurements of differential dijet cross sections as function of the fraction of photon’s momentum invested in the dijet system are presented. The dependence of the cross sections on the virtuality of the photon and mean transverse energy squared of the two leading jets has been investigated. QCD calculations based on current parametrizations of the real and virtual photon parton distribution functions have been compared to the data.

Studies of Real and Virtual Photon Structure at HERA
For the H1 and ZEUS Collaborations Recent results of real and virtual photon structure from the H1 and ZEUS collaborations are discussed. Jet cross-sections in photoproduction processes provide new constraints on the real photon parton densities. Measurements of dijet cross-sections in deep-inelastic scattering show clear evidence for a resolved component to the virtual photon which is suppress...
متن کاملVirtual Photon Structure at Hera
Measurements of the structure of the virtual photon in the transition region between quasi-real photons and those far from mass-shell have been made with the ZEUS detector at HERA, using an integrated luminosity of 38 pb. Dijet final states are identified, and differential cross sections are presented in terms of x γ , an estimator of the fraction of the photon energy which takes part in the QC...
متن کاملReview of High Energy Diffraction in Real and Virtual Photon Proton scattering at HERA
The electron-proton collider HERA at DESY opened the door for the study of diffraction in real and virtual photon-proton scattering at center-of-mass energies W up to 250 GeV and for large negative mass squared −Q2 of the virtual photon up to Q = 1600 GeV. At W = 220 GeV and Q = 4 GeV, diffraction accounts for about 15% of the total virtual photon proton cross section decreasing to ≈ 5% at Q = ...
