The unpolarized semi-inclusive deep-inelastic scattering (SIDIS) differential cross sections in He3(e,e′π±)X have been measured for the first time in Jefferson Lab experiment E06-010 with a 5.9GeVe− beam on a He3 gas target. The experiment focuses on the valence quark region, covering a kinematic range 0.12
