High energy neutrino in a nuclear environment: mirror asymmetry of the shadowing effect
Zoller, V. R.
Original · EN
The parity non-conservation effect in diffractive charged current DIS is quantified in terms of color dipole sizes of left-handed and right-handed electroweak bosons. We identify the origin and estimate the strength of the left-right asymmetry effect and present comparison with experimental data on the parity-odd structure function ΔxF₃ =xF₃νⁿ-xF₃νN. We study the shadowing effect in absorption of left-handed and right-handed W-bosons by 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 s dipole with λ=-1.
