Theoretical Evaluation on Inelastic Lepton Scattering of Nuclear Effects.

deep-inelastic lepton-hadron scattering

The most important part of the order α s corrections to the charm component of the charged-current structure functions F2(x,Q ) and F3(x,Q ) have been calculated. This calculation is based on the asymptotic form of the heavy-quark coefficient functions corresponding to the higher order corrections to the W-boson-gluon fusion process. These coefficient functions which are in principle only valid...

Inelastic Lepton Scattering in Gluon Models*

A formal study of quark models with interactions due to scalar, pseudoscalar or vector fields is presented. It is shown that all the results which have been derived in quark parton models in which the details of the nucleonls constitution are not specified can be obtained formally using naive canonical manipulations of operators. In the case that there is no vector field some new results are ob...

Quasielastic versus Inelastic and Deep Inelastic Lepton Scattering in Nuclei

We have made a thorough investigation of the nuclear structure function W2A in the region of 0.8 < x < 1.5 and Q2 < 20 GeV2, separating the quasielastic and inelastic plus deep inelastic contributions. The agreement with present experimental data is good giving support to the results for both channels. Predictions are made in yet unexplored regions of x and Q2 to assert the weight of the quasie...

Inelastic Charged - Lepton Scattering off Nucleons * _ Clemens

Note on Shadowing and Diffraction in Deep - Inelastic Lepton Scattering ∗ )

We discuss the close relation between shadowing in deep-inelastic lepton-nucleus scattering and diffractive photoand leptoproduction of hadrons from free nucleons. We show that the magnitude of nuclear shadowing at small Bjorken-x, as measured by the E665 and NMC collaborations, is directly related to HERA data on the amount of diffraction in the scattering from free nucleons. ———————————— ) Wo...
