Fragmentation Functions at ZEUS

Talk given at the 5th International Workshop on Deep Inelastic Scattering
and Related Phenomena, Chicago, April, 1997

Abstract:

The scaled momentum spectra of final state charged hadrons produced in Deep Inelastic Scattering in the ranges 10 < Q2 < 1280 GeV2 and $ 6~.~ 10^{-4} < x_{\mbox{{\tiny Bjorken}}} < 5~.~ 10^{-2}$ have been measured in the current region of the Breit frame using the ZEUS detector. The evolution with Q2 of the scaled momentum, $x_p = 2p^{\mbox{{\tiny Breit}}}/Q$, has been investigated and preliminary results are presented which show evidence for scaling violations and support for the universality of quark fragmentation.
