We discuss whether the NuTeV anomaly can be explained, compatibly with allother data, by QCD effects (maybe, if the strange sea is asymmetric, or thereis a tiny violation of isospin), new physics in propagators or couplings of thevector bosons (not really), loops of supersymmetric particles (no), dimensionsix operators (yes, for one specific SU(2)-invariant operator), leptoquarks(not in a minimal way), extra U(1) gauge bosons (maybe: an unmixed Z' coupledto B-3L_mu also increases the muon g-2 by about 10^{-9} and gives a `burst' tocosmic rays above the GZK cutoff).Comment: 22 pages, 4 figures. Final version; note added about oscillations. Version 4: note added at page 20 (not present in the published version), about QCD interpretations of the NuTeV anomal
