Nuclear effects in the deuteron structure function

An analysis of nuclear effects in the deuteron quark distributions is carried out in connection with the Gottfried sum rule (GSR), the Drell-Yan proton-neutron asymmetry and the Bjorken sum rule (BSR). It is shown that the small amount of nuclear effects necessary to saturate the GSR experimental data modifies the Drell-Yan asymmetry in an entirely different way as an asymmetric sea does. These effects are of little consequence in the convergence of the BSR to the expected value. (orig.)
