Measurement of the EMC effect in light and heavy nuclei

NUCLEAR REACTIONS 2H, 3,4He, 9Be, 12C, 63Cu, 197Au(e, e'), E=5.77 GeV; measured scattered electrons using high momentum spectrometer (HMS), a magnetic focusing spectrometer at the Thomas Jefferson National Accelerator facility; deduced charge symmetric background, differential σ, magnitude of isoscalar corrections, EMC (European Muon Collaboration effect) ratios; analyzed present data combined with those from SLAC and CLAS. Cross sections listed in Supplemental Material. Relevance to atomic mass A-dependence of the EMC effect of nuclear structure functions differing significantly from the sum of proton and neutron distributions.

Measurements of the separated longitudinal structure function FL from hydrogen and deuterium targets at low Q2

NUCLEAR REACTIONS 1,2H(e, e'), E=2.24, 3.04, 4.41, 5.50 GeV; measured scattered electrons, differential σ(E, θ) using the high momentum spectrometer (HMS) and the short orbit spectrometer (SOS) at CEBAF-Thomas Jefferson National Accelerator (JLab) facility; deduced structure functions and longitudinal structure functions for protons and deuterons using Rosebluth separation technique, smaller longitudinal structure function and a smaller ratio of longitudinal to transverse cross section for deuteron than the proton, possible suppression of the gluonic distribution in nuclei. Comparison with parametrizations, previous experimental data, and theoretical predictions extrapolated to the beam energies investigated.
