Description

I will review nuclear effects on neutrino-nucleus deeply inelastic scattering (DIS) and discuss the nuclear parton distributions functions (NPDFs). Due to the weak interaction, heavy nuclear target is needed to get high accuracy of the measurements. The nuclear effects on the structure function must be taken into account. These effects are already known by charged lepton-nucleus DIS experiments. In the ratio of the structure functions obtained by nucleus and deuteron targets; $R^A(x)=F_2^A(x)/F_2^D(x)$, these effects show the following behavior: $R^A(x)<1$ for $x<0.07$ (shadowing effect) $R^A(x)>1$ for $0.1<x<0.3$ (anti-shadowing effect) $R^A(x)<1$ for $0.3<x<0.8$ (EMC effect) $R^A(x)>1$ for $0.8
