Abstract
Data from e
+e
− annihilations at 29 GeV have been used to measure the production cross section and fragmentation function of
η mesons. The signal is observed in the
η→
γγ decay channel. The fragmentation for
p
η
>1.5 GeV/
c agrees well with the prediction of the Lund model, whereas the prediction of the Webber model lies above the data. The mean multiplicity is measured to be 〈
n
η
〉=0.58±0.10
η mesons per hadronic event, of which 0.51 represents the direct production of
η and
η′ mesons in the fragmentation chain.
