Deep inelastic pion electroproduction at threshold

Scaling 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.

Threshold pion electroproduction at large momentum transfers

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 ...

Heavy-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...

Studies of Hadronization Mechanisms using Pion Electroproduction in Deep Inelastic Scattering from Nuclei

Atomic nuclei can be used as spatial analyzers of the hadronization process in semi-inclusive deep inelastic scattering. The study of this process using fully-identified final state hadrons began with the HERMES program in the late 1990s, and is now continuing at Jefferson Lab. In the measurement described here, electrons and positive pions were measured from a 5 GeV electron beam incident on t...
