Hadron Multiplicities at HERMES

TL;DR

This paper reports measurements of hadron multiplicities in deep-inelastic scattering of 27.5 GeV positrons off hydrogen, providing data for various mesons over a range of kinematic variables during the 2000 HERA run.

Contribution

It presents new experimental data on hadron multiplicities in deep-inelastic scattering at HERA, covering multiple meson types and kinematic ranges.

Findings

Measured multiplicities for $ angle$, $ angle$, $ angle$, $ angle$ mesons.

Data covers 0.15$< z <$0.9 and $<Q^2>$ = 2.5 GeV$^2$.

Abstract

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$^2$.
