Left and Right in small-x neutrino DIS
Abstract
Description
The color dipole analysis of nuclear effects in charge current DIS is presented. The emphasis is put on the pronounced effect of left-right asymmetry of shadowing in neutrino-nucleus DIS at small values of Bjorken $x$. Strikingly different scaling behavior of nuclear shadowing for the left-handed andright-handed $W^+$ is predicted. Large, about 25%, shadowing in the $Fe$ structure functions is predicted, which is important for a precise determination of the P-odd nucleon structure functions $xF^{ν(\barν)}_3$ and $Δx F_3=xF_3^ν-xF_3^{\bar ν}$.
