Study of Nuclear Effects in Nucleon Structure Functions Up to and Beyond the Kinematic Limit

摘要

An experiment on deep inelastic muon nucleon scattering is proposed to carried out in order to study the x-dependence (where x is the Bjorken variable) of nucleon structure functions and their ratios over a range of squared four-momentum transfers Q sup 2 =50-200 GeV sup 2 and x=0.4-2.0. Such measurements performed on a number of nuclei with atomic weights from 2 to 207 would provide new information for detailed studies of the EMC effect and tests of many models explaining the x behaviour of the nucleon structure functions and their ratios. The measurements will be decisive for the proof that a quark-parton model of the nucleus describes adequately nuclear structure probed at high energies. The upgraded high luminosity spectrometer with improved resolution in transferred energy will be used for the measurements. 31 refs.; 21 figs.; 1 tab. (Atomindex citation 17:086013)
