Novel QCD Phenomena in Deep Inelastic Lepton Scattering
I discuss several novel phenomenological features of QCD which are observable in deep inelastic lepton-nucleon and lepton-nucleus scattering. Initialand final-state interactions from gluon exchange, normally neglected in the parton model, have a profound effect on QCD hard-scattering reactions, leading to leading-twist single-spin asymmetries, the diffractive contribution to deep inelastic scat...
متن کاملdeep-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...
متن کاملQuasielastic 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...
متن کاملNote 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...
متن کاملThe Nucleon’s Virtual Meson Cloud and Deep Inelastic Lepton Scattering
We address the question whether the nucleon’s antiquark sea can be attributed entirely to its virtual meson cloud and, in essence, whether there exists a smooth transition between hadronic and quark-gluon degrees of freedom. We take into account contributions from π and K mesons and compare with the nucleon’s antiquark distributions which serve as a non-perturbative input to the QCD evolution e...
