Abstract

We present results from a study of high-momentum inclusive hadron production in electron-positron interactions at

\sqrt{s} = 3.8 and 4.8

GeV. Comparison of the momentum spectra at these energies shows no scaling violation in the region

x (= \frac{E}{E_{beam}}) > 0.7

. At

\sqrt{s} = 4.8

GeV the

\frac{K}{π}

ratio for hadrons with momenta >1.1 GeV/c is 0.27±0.08, and the average number of charged hadrons is 3.6±0.3 for those events which have at least one charged hadron with momentum greater than 1.1 GeV/c.
