Inelastic Scattering from 20Ne

Inelastic scattering from quantum impurities

We review the non-perturbative theoretical framework set up recently to compute the inelastic scattering cross section from quantum impurities [G. Zaránd et al., Phys. Rev. Lett. 93, 107204 (2004)] and show how it can be applied to a number of quantum impurity models. We first use this method for the S = 1/2 single-channel Kondo model and the Anderson model. In both cases, a large plateau is fo...

Nuclear PDFs from neutrino deep inelastic scattering

We study nuclear effects in charged current deep inelastic neutrino–iron scattering in the framework of a χ-analysis of parton distribution functions. We extract a set of iron PDFs and show that under reasonable assumptions it is possible to constrain the valence, light sea and strange quark distributions. We compare our results with nuclear parton distribution functions from the literature and...

Polarised Quark Distributions from Deep Inelastic Scattering

Polarised quark distributions are extracted from semi-inclusive deep inelastic scattering data, which include the additional detection of a leading hadron to providestatisticaìàvour-tagging'. Results are combined from both proton and`neutron' targets to isolate the contributions to the nucleon spin of the individual quark avours, including the sea quarks. Spin asymmetries in the semi-inclusive ...

Deep Inelastic Scattering from Light Nuclei

For the past 20 years the nuclear EMC effect — the nuclear medium modification of the nucleon structure functions — has posed a serious challenge to models of the nucleus which involve quark degrees of freedom. Although the basic features of the EMC effect can be understood within a conventional nuclear physics framework, a quantitative description over the entire range of Bjorken-x appears bey...
