Hadron Multiplicities at HERMES
  Hadron multiplicities of $\pim$, $\pip$, $\km$ and $\kp$ have been measured in the deep-inelastic scattering of 27.5 GeV positrons off a hydrogen target. The data used in this analysis have been collected during the 2000 HERA running period. The multiplicities were obtained for 0.15$< z <$0.9 for $<Q^2>$ = 2.5 GeV$^2$.
