Left-right asymmetry of nuclear shadowing in charged current DIS

Abstract

We study the shadowing effect in highly asymmetric diffractive interactions of left-handed and right-handed W-bosons with atomic nuclei. The target nucleus is found to be quite transparent for the charmed-strange Fock component of the light-cone W^+ in the helicity state λ=+1 and rather opaque for the c\bar s dipole with λ=-1. The shadowing correction to the structure function ΔxF_3 = xF_3^{νN}-xF_3^{\barνN} extracted from νFe and \barνFe data is shown to make up about 20% in the kinematical range of CCFR/NuTeV.
