read the original abstract

Multiplicities in semi-inclusive deep-inelastic scattering are presented for each charge state of \pi^\pm and K^\pm 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 x_B, Q^2, z, and P_h\perp. 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.

  1. Determination of Fragmentation Functions from Charge Asymmetries in Hadron Production

    hep-ph 2025-07 unverdicted novelty 7.0

    Non-singlet fragmentation functions of pions and kaons are determined at NNLO QCD from charge asymmetry measurements in e+e- annihilation and SIDIS, yielding a scaling index of 0.7 and strangeness suppression of 0.5.

  2. Measurements of transverse-momentum dependent effects in semi-inclusive DIS at COMPASS

    hep-ex 2026-05 unverdicted novelty 4.0

    New COMPASS data from polarized deuteron targets reduce uncertainties on d-quark transversity by a factor of 2.5 at large Bjorken x and will enable first extraction of the Boer-Mulders function from unpolarized nucleon data.
