Book Description
Experiment E89-008 measured inclusive electron scattering cross sections from different nuclei in Hall C at Jefferson Laboratory. Cross sections on the low energy loss side of the quasi-elastic peak (xBj > 1) are extracted for carbon, aluminum, iron and gold. The data cover four-momentum transfers squared of 0.97 to 5.73 GeV 2 =c 2 . The measured cross sections are compared to cross sections calculated using a microscopic spectral function. The cross section results are also analyzed in terms of the two scaling functions F (y) and f(?'). For both the data is found to be independent of the momentum transfer (scaling of the first kind). For f(?') the data is in addition independent of the mass number A (scaling of the second kind) and thus exhibits superscaling properties.

Book Description
CEBAF experiment e89-008 measured inclusive electron scattering from nuclei in a Q2 range between 0.8 and 7.3 (GeV/c)2 for x{sub Bjorken} approximately greater than 1. The cross sections for scattering from D C, Fe, and Au were measured. The C, Fe, and Au data have been analyzed in terms of F(y) to examine y-scaling of the quasielastic scattering, and to study the momentum distribution of the nucleons in the nucleus. The data have also been analyzed in terms of the structure function vW2 to examine scaling of the inelastic scattering in x and xi and to study the momentum distribution of the quarks. In the regions where quasielastic scattering dominates the cross section (low Q2 or large negative values of y), the data are shown to exhibit y-scaling. However, the y-scaling breaks down once the inelastic contributions become large. The data do not exhibit x-scaling, except at the lowest values of x, while the structure function does appear to scale in the Nachtmann variable, xi.

Book Description
This book focuses on the latest theoretical and experimental results and future perspectives regarding electromagnetic and hadronic physics at intermediate energies. Nucleon form factors and spin structure functions, deep-inelastic scattering, excited baryons and mesons, and correlations in nuclei are discussed. Many new results and the scientific programmes of the different laboratories in Europe and North America are also presented. A special section is devoted to relativistic approaches to hadrons and nuclei at intermediate energies.

Book Description
The purpose of this volume is to gather the latest experimental results from the H1, ZEUS and HERMES collaborations and to capture new trends in HERA phenomenology. The presentations are by experts for experts, but are suitable for a mixed readership of both theoreticians and experimentalists. H1 members also cover ZEUS results and vice versa. This is the place where discrepancies between experimental data and theoretical predictions are pointed out and ventilated and where projects to be launched in the future are identified.
