Abstract

Cross sections for inelastic scattering of electrons from hydrogen were measured for incident energies from 7 to 17 GeV at scattering angles of 6° to 10° covering a range of squared four-momentum transfers up to 7.4 (GeV/c)2. For low center-of-mass energies of the final hadronic system the cross section shows prominent resonances at low momentum transfer and diminishes markedly at higher momentum transfer. For high excitations the cross section shows only a weak momentum-transfer dependence.

Landmarks—Discovery of Particles inside the Proton

Published 1 August 2014

High-energy collisions between electrons and protons produced the first indications, published in 1969, that smaller constituent particles lurked inside protons.
