摘要：
We study the shadowing effect in highly asymmetric diffractive interactions of left- 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. lambda = +1 and rather opaque for the c. dipole with lambda = -1. The shadowing correction to the structure function Delta xF(3) = xF(3)(vN) - xF(3)(vN) extracted from vFe and v ($) over bar Fe data is shown to make up about 20% in the kinematical range of CCFR/NuTeV.
