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.

متن کاملDeep - 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 کاملStudies 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...
متن کاملPion fluctuation in deep inelastic scattering
The forward neutron production in the ep collisions at 300 GeV measured by the H1 and ZEUS Collaborations at DESY has been used to estimate the total probability for the proton fluctuation into nπ and pπ. The probability found is on the order of the 30%. This number is compared with the numbers of obtained for the probability of quark fluctuation into π from several alternative DIS processes (G...
