Moments of nuclear and nucleon structure functions at low Q{sup 2} and the momentum sum rule

New nuclear structure function data from Jefferson Lab covering the higher-x and lower-Q{sup 2} regime make it possible to extract the higher-order F{sub 2} moments for iron and deuterium at low four-momentum transfer squared Q{sup 2}. These moments allow for an experimental investigation of the nuc...

Zusammenfassung:	New nuclear structure function data from Jefferson Lab covering the higher-x and lower-Q{sup 2} regime make it possible to extract the higher-order F{sub 2} moments for iron and deuterium at low four-momentum transfer squared Q{sup 2}. These moments allow for an experimental investigation of the nuclear momentum sum rule and a direct comparison of the nonsinglet nucleon moment with lattice QCD results.
