โฆ Synopsis
The central role of soft nucleon matrix elements in reactions of high energy electrons or real photons with nucleons is emphasized. These soft matrix elements are described in terms of skewed parton distributions. Their connections to ordinary parton distributions, form factors, Compton scattering and hard meson electroproduction is discussed.

We study the low energy expansion of the nucleon's electroweak form factors in the framework of an effective chiral Lagrangian including pions, nucleons and the A(1232). We work to third order in the so-called small scale expansion and compare the results with the ones previously obtained in the chi
The inelastic scattering of thermal neutrons from liquid helium at 1.2 K has been measured for wave-vector transfers in the range 6.0 ~ Q ~ 12.0 A-1 Oscillations in the widths of the scattered-neutron distributions as a function of Q are observed to persist at least up to 12.0 A-~. A simple physical
