Lepton-Quark Physics Yet to Be Studied by Electron Synchrotrons at Energies of Order 1 GeV

摘要

Several photoproduction processes are briefly discussed for experiments yet to be performed by electron synchrotrons at energies of order 1 GeV, in which ''lepton-quark physics'' can be studied. They include 1) lepton-pair production, 2) pion-pair production, 3) (forward) triple-pion production, and 4) (forward) photon-pair production, all by photons. Especially, inelastic virtual Compton scattering of photons from nucleons for lepton-pair production, gamma + p(n) implies gamma * + anything and gamma * implies l exp + + l exp - , is proposed and discussed in some detail to study not only the quark structure of the nucleon but that of the photon.
