Abstract
TheW andQ 2 dependence of the transverse momentum of the forward-going hadrons in deep inelastic neutrino charged current interactions on neon is studied. The data were obtained by exposing BEBC filled with a Ne/H2 mixture to the CERN SPS wide-band neutrino beam. The data on average transverse momentum are compared to a model which includes first order QCD, intrinsic quark momentum in the nucleon and Fermi motion, as well as a simple model for hadronization. The model is found to describe the data well. Values of α s =0.16±0.02(stat)±0.02(syst.)±0.03(frag.) at an averageQ 2 of 15.4±0.4 GeV2/c2 and\(\Lambda _{\overline {MS} } = 216_{ - 99}^{ + 113} \) (stat.) +100−90 (syst.) +130−90 , (frag.) MeV/v for three flavours are extracted.
