Abstract

The unpolarized semi-inclusive deep-inelastic scattering (SIDIS) differential cross sections in 3He(e,e′π±)X have been measured for the first time in Jefferson Lab experiment E06-010 with a 5.9 GeV e− beam on a 3He gas target. The experiment focuses on the valence quark region, covering a kinematic range 0.12 \u3c xbj \u3c 0.45, 1 \u3c Q2 \u3c 4 (GeV/c)2, 0.45 \u3c zh \u3c 0.65, and 0.05 \u3c Pt \u3c 0.55 GeV/c. The extracted SIDIS differential cross sections of π± production are compared with existing phenomenological models while the 3He nucleus approximated as two protons and one neutron in a plane-wave picture, in multidimensional bins. Within the experimental uncertainties, the azimuthal modulations of the cross sections are found to be consistent with zero
