Determination of alpha(S) from the Transverse Momenta of Hadrons Produced inNeutrino and Antineutrino Interactions

摘要

The W and Q(2) dependence of the transverse momentum of the forward going hadronsin deep inelastic neutrino charged current interactions on neon is studied. The data were obtained by exposing the Big European Bubble Chamber (BEBC) filled with an Ne/He mixture to the CERN SPS wideband neutrino beam. The data on average transverse momentum are compared to a model which includes first order quantum chromodynamics, intrinsic quark momentum in the nucleon and Fermi motion, as well as a simple model hadronization. The model describes the data well.
