Abstract

Multiplicities in semi-inclusive deep-inelastic scattering are presented for each charge state of π± and K± mesons. The data were collected by the HERMES experiment at the HERA storage ring using 27.6 GeV electron and positron beams incident on a hydrogen or deuterium gas target. The results are presented as a function of the kinematic quantities xB, Q2, z, and Ph⊥. They represent a unique data set for identified hadrons that will significantly enhance our understanding of the fragmentation of quarks into final-state hadrons in deep-inelastic scattering.
