Symposium on Hadron Spectroscopy

By J. Gilman


* Work supported by the U. S. Atomic Energy Commission.-l-High energy inelastic electron-nucleon scattering probes the instantaneous charge distribution of the nucleon and provides a method for investigating possible substructure. In the year that has passed since the International Symposium on Electron and Photon Interactions at High Energies at Liverpool, a number of important developments have taken place in both the experimental and theoretical aspects of inelastic electron-nucleon scattering, ā€™ The Kiev conference has, in particular, seen the discussion of a large amount of new data from SUC, including data on both electron-proton and electron-neutron inelastic scattering. 2 I propose to discuss here these developments, with particular attention to some theoretical consequences of the recent experimental data and to recent work on duality and resonance behavior. A discussion of other aspects of inelastic lepton-hadron scattering and related processes can be found in the proceedings of the Liverpool Symposium and the more recent Naples meeting. 3 The process of inelastic electron-nucleon scattering is shown in Figure 1 where an electron (with energy E) is incident on a nucleon (of four-momentum P) and scatters (with resulting final energy Eā€™) by an angle f3 due to the exchange of a single photon (of four-momentum q). If we do not observe the hadronic final state, as is the case in most of the experiments done until very recently, then the double differential cross section can be written a
