Description
I report our recent studies on nuclear structure functions. First, nuclear parton distribution functions are determined by analyzing high-energy nuclear reaction data. Using charged-lepton and neutrino scattering data, we investigate whether there are significant differences between nuclear modifications in the charged-lepton and neutrino reactions. This issue was first pointed out by the nCTEQ collaboration. Second, nuclear effects on the polarized structure function $b_1$ are investigated in the deuteron. It is important to show theoretical estimates at this stage because an experimental proposal was approved at JLab to measure $b_1$. The studies could open a new field of spin physics for spin-one hadrons.
