A Simple Model for Nuclear Modification of Parton Distribution Functions / A.V.Kotikov, A.V.Lipatov. – Text : electronic // Chinese Physics C. – 2026. – Vol. 50, No. 3. – P. 034109. – URL: https://doi.org/10.1088/1674-1137/ae25ca. – Bibliogr.: 99.
A model for the nuclear medium modification of parton densities is presented. The approach is based on a global analysis of available deep inelastic scattering data for different nuclear targets within the rescaling model, combined with the effects of Fermi motion. The scale dependence is implemented through the DGLAP-evolved quark and gluon densities in a proton derived analytically at the leading order of QCD coupling. By fitting the rescaling parameters to experimental data on the ratio F&sup(A)&sub(2)(xQ*2)/F&sup(A')&sub(2)(x,Q*2) for several nuclear targets A and A', we obtain predictions for nuclear parton distributions, even for unmeasured nuclei. The effects of nuclear modifications are investigated with respect to the mass number A. We highlight distinct shadowing and antishadowing behaviors for gluons and quarks.
