| Description: |
Measurements of semi-inclusive deep-inelastic scattering multiplicities for and from proton and deuteron targets are reported on a grid of hadron kinematic variables , and for leptonic kinematic variables in the range and . Data were acquired in 2018 and 2019 at Jefferson Lab Hall C with a 10.6 GeV electron beam impinging on 10-cm-long liquid hydrogen and deuterium targets. Scattered electrons and charged pions were detected in the High Momentum Spectrometer and Super High Momentum Spectrometer, respectively. The multiplicities were fitted for each bin in to extract the —independent and the azimuthal modulations and . The dependence of the results was found to be remarkably consistent for the four cases studied: over the range , as were the multiplicities evaluated near over the extended range . The Gaussian widths of the P t dependence exhibit a quadratic increase with z . The cos ( ϕ * ) modulations were found to be consistent with zero for π + , in agreement with previous world data, while the π − moments were, in many cases, significantly greater than zero. The cos ( 2 ϕ ... |
