Abstract

We extract the high-twist contribution to the neutrino-nucleon structure fu nction xF(3)((v+(v) over bar )N) from the analysis of the data collected by the IHEP-JINR Neutrino Detector in the runs with the focused neutrino beam s at the IHEP 70 GeV proton synchrotron. The analysis is performed within t he infrared renormalon (IRR) model of high twists in order to extract the n ormalization parameter of the model. From the NLO QCD fit to our data we ob tain the value of the IRR model normalization parameter Lambda (2)(3) = 0.6 9 +/- 0.37 (exp) +/- 0.16 (theor) GeV2. We also obtain Lambda (2)(3) = 0.36 +/- 0.22 (wxp) +/- 0.12 (theor) GeV2 from a similar fit to the CCFR data. The average of both results is Lambda (2)(3) = 0.44 +/- 0.19 (exp) GeV2.
