Abstract

The multiplicities of positive and negative pions, kaons, and unidentified hadrons produced in deepinelastic scattering are measured in bins of the Bjorken scaling variable x, the relative virtual-photon energy y, and the fraction of the virtual-photon energy transferred to the final-state hadron z. Data were obtained by the COMPASS Collaboration using a 160 GeV muon beam of both electric charges and a liquid hydrogen target. These measurements cover the kinematic domain with photon virtuality Q² > 1 ðGeV=cÞ² 0.004 < x < 0.4, 0.1 < y < 0.7, and 0.2 < z < 0.85, in accordance with the kinematic domain used in earlier published COMPASS multiplicity measurements with an isoscalar target. The calculation of radiative corrections was improved by using the Monte Carlo generator DJANGOH, which results in up to 12% larger corrections in the low-x region.

N2 - The multiplicities of positive and negative pions, kaons, and unidentified hadrons produced in deepinelastic scattering are measured in bins of the Bjorken scaling variable x, the relative virtual-photon energy y, and the fraction of the virtual-photon energy transferred to the final-state hadron z. Data were obtained by the COMPASS Collaboration using a 160 GeV muon beam of both electric charges and a liquid hydrogen target. These measurements cover the kinematic domain with photon virtuality Q2 > 1 ðGeV=cÞ2 0.004 < x < 0.4, 0.1 < y < 0.7, and 0.2 < z < 0.85, in accordance with the kinematic domain used in earlier published COMPASS multiplicity measurements with an isoscalar target. The calculation of radiative corrections was improved by using the Monte Carlo generator DJANGOH, which results in up to 12% larger corrections in the low-x region.
