Description

Evidence for a significant higher twist contribution to high zπ- production in antineutrino scattering is presented. In events with W>3 GeV and Q2>1 GeV2 in our data, it accounts for (51+-8)% of all π- with z above 0.5. It is consistent with the z-Q2 correlations of Berger's higher twist prediction. The data are inconclusive concerning the predicted y-z correlation and psub(T) dependence. The z-Q2 correlation is not adequately described by the Lund Monte-Carlo. (orig.)
