It introduces an integrated approach combining QCD-based nucleon structure functions with multiple nuclear effects, highlighting their dependence on neutrino type and C-parity.

Findings

Nuclear effects vary with neutrino type and C-parity.

Nuclear corrections influence the Adler and Gross-Llewellyn-Smith sum rules.

The approach provides detailed insights into nuclear modifications of structure functions.

Abstract

We discuss calculation of nuclear corrections to the structure functions for the deep-inelastic scattering of muon and (anti)neutrino. Our approach includes a QCD description of the nucleon structure functions as well as the treatment of Fermi motion and nuclear binding, off-shell correction to bound nucleon structure functions, nuclear pion excess and nuclear shadowing. We emphasize the dependence of nuclear effects on the type and C-parity of (anti)neutrino structure functions. We also examine the interplay between different nuclear effects in the Adler and the Gross-Llewellyn-Smith sum rules for nuclei.
