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 < xbj < 0.45, 1 < Q2< 4 (GeV /c)2, 0.45 < zh < 0.65, and 0.05 < Pt < 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.
