νN, μN interactions: Structure functions, higher twist

Data on deep inelastic scattering of leptons by nucleons and nuclei have been accumulated for several years. Results exist from several experiments with electron, muon, neutrino beams. In this talk I shall review the most recent experiments which measured nucleon structure functions with ..nu.. and ..mu.. beams. In particular, I will summarize the results on R = sigma/sub L//sigma/sub T/ measurement, on F/sub 2/(x,Q/sup 2/), and xF/sub 3/(x,Q/sup 2/), and their interpretation in terms of QCD, including both gluon radiation and higher twist phenomena.
