Abstrakt: Evidence for a significant higher twist contribution to highz p- production in antineutrino scattering is presented. In events withW>3 GeV andQ2>1 GeV2 in our data, it accounts for (51 ±8)% of all p- withz above 0.5. It is consistent with thez-Q2 correlations of Berger's higher twist prediction. The data are inconclusive concerning the predictedy-z correlation andpT dependence. Thez -Q2 correlation is not adequately described by the Lund Monte-Carlo.
