Abstract:
The deep-inelastic deuteron structure function (SF) F2D in the covariant approach in the light-cone variables is considered. The neutron SF F2n is extracted from the deuteron and proton experimental data taking into account the relativistic deuteron model and the parametrization of F2n is obtained. The effect of the relativistic Fermi motion is estimated to be 6% at x0.7. The extracted neutron SF is used to verify the Gottfried sum rule. It is shown that the violation of the flavour symmetry of the sea can be large with increasing Q2.
