Deep - Inelastic Electroproduction ” Slac - Pub
The regent data’ on W2&/Wip w =BMv/Q indicates that perhaps WZn/WZp -0 as -1. This corn ine with the data on neutrino cross s&ions cbegin to put naive parton-model calculations in trouble, a point emphasized by Nat htmann . 2 Let us assume the validity of the kindergarten parton calculati.ons . Then oS/oT small requires J=1/2 partons to have the dominant contribution. Assume only J=1/2 partons ...
متن کاملHeavy-quark correlations in deep-inelastic electroproduction
We have completed the next-to-leading order perturbative QCD corrections to the virtual-photon exclusive differential cross sections for heavy quark production in deep-inelastic electron-proton scattering, i.e. e + P → Q +Q +X . Using these results, we have computed distributions which are sensitive to correlations among the heavy quark, the heavy antiquark, and the associated jet. Some predict...
متن کاملScaling in Deep Inelastic Pion Electroproduction*
An attempt is made to apply a light cone dominance technique to the deep inelastic el ec troproduc tion of pions. A scaling law is derived which is in agreement with preliminary data.

متن کاملDeep-Inelastic Electroproduction of Neutrons in the Proton Fragmentation Region
Experiments at HERA looking for deep-inelastic electroproduction of neutrons in the proton fragmentation region are in progress. They are aimed to measure the pion structure function at small Bjorken x. The important condition for such a study is to establish under what kinematical conditions the dominance of the pion-pole graph in the process is guaranteed. We analyse other sources of the lead...
متن کاملSingle-Spin Beam Asymmetry in Semi-Exclusive Deep-Inelastic Electroproduction
Recent measurements from Jefferson Lab show significant beam single spin asymmetries in deep inelastic scattering. The asymmetry is due to interference of longitudinal and transverse photoabsorption amplitudes which have different phases induced by the final-state interaction between the struck quark and the target spectators. We developed a dynamical model for a single-spin beam asymmetry in d...
