Quark-parton model for the structure function W/sub 2/ of the proton and neutron in their rest systems

Journal Article · · Phys. Rev., D; (United States)
The deep-inelastic structure function W/sub 2/ is calculated using the impulse approximation for mass-shell partons in the target-nucleon rest system. Bjorken scaling and the approach to scaling are shown to follow from parton kinematics in the rest system. The partons are identified as quarks and a simple harmonic-oscillator quark model is used to fit the proton and neutron structure functions down to x approx. 0.1. The neutron structure function requires an inherently non-SU(6) quark model based on relative coordinates that we argue should replace shell-model SU(6) quark models that have been used extensively.
