Description

An analysis is presented of the z distributions of secondary hadrons produced in 5600 charged current events from a BEBC neutrino-hydrogen experiment. Evidence is presented for scaling deviations in the z distributions and a breakdown of factorization in the single particle inclusive cross-sections. The results are consistent with the leading order QCD predictions on the q2 dependence of non-singlet moments of quark fragmentation functions, yielding a value of Λ approximately 0.6 GeV. (orig.)
