Query: Nuclear parton distribution functions and their effects on sin^2 theta_W
  anomaly   Nuclear parton distribution functions (NPDFs) are investigated by analyzing
the data on structure functions F_2^A and Drell-Yan cross sections
sigma_{DY}^{pA}. An important point of this analysis is to show uncertainties
of the NPDFs by the Hessian method. The analysis indicates that the
uncertainties are large for antiquark distributions at x>0.2 and gluon
distributions in the whole x region. We also discuss a nuclear effect on the
NuTeV sin^2 theta_W anomaly as an application.
