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 5.9GeV e- beam on a ³He gas target. The experiment focuses on the valence quark region, covering a kinematic range 0.12<x_bj<0.45,1<Q²<4(GeV/c)²,0.45<z_h<0.65, and 0.05<P_t<0.55GeV/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. © 2017 American Physical Society.
