Chronology of Milestone Events in Particle Physics

  Nobel prize to J. I. Friedman, H. W. Kendall, and R. E. Taylor awarded in 1990 "for their pioneering investigations concerning deep inelastic scattering of electrons on protons and bound neutrons, which have been of essential importance for the development of the quark model in particle physics''

Results of electron-proton inelastic scattering at 6 and 10 are discussed, and values of the structure function W2 are estimated. If the interaction is dominated by transverse virtual photons, W2 can be expressed as a function of = 2M /q2 within experimental errors for q2 > 1 (GeV/c)2 and > 4, where is the invariant energy transfer and q2 is the invariant momentum transfer of the electron. Various theoretical models and sum rules are briefly discussed.
