Determination of the parton distributions and structure functions of the proton from neutrino and antineutrino reactions on hydrogen and deuterium
Zeitschrift für Physik C Particles and Fields 62:4 (1994) 575-600
Abstract:
This analysis is based on data from neutrino and antineutrino scattering on hydrogen and deuterium, obtained with BEBC in the (anti) neutrino wideband beam of the CERN SPS. The parton momentum distributions in the proton and the proton structure functions are determined in the range 0.01Determination of the ratio rv =dv uv of the valence quark distributions in the proton from neutrino and antineutrino reactions on hydrogen and deuterium
Zeitschrift für Physik C Particles and Fields 62:4 (1994) 601-607
Abstract:
Based on a QCD analysis of the parton momentum distributions in the proton, the ratio rv=dv/uv of the d and u valence quark distributions is determined as function of x in the range 0.01Comparison of energy flows in deep inelastic scattering events with and without a large rapidity gap
Physics Letters B 338:4 (1994) 483-496
Abstract:
Energy flows in deep inelastic electron-proton scattering are investigated at a centre-of-mass energy of 269 GeV for the range Q2 ≥ 10 GeV2 using the ZEUS detector. A comparison is made between events with and without a large rapidity gap between the hadronic system and the proton direction. The energy flows, corrected for detector acceptance and resolution, are shown for these two classes of events in both the HERA laboratory frame and the Breit frame. From the differences in the shapes of these energy flows we conclude that QCD radiation is suppressed in the large-rapidity-gap eents compared to the events without a large rapidity gap. © 1994.Measurement of the cross section for gamma gamma -->pp-bar.
