Charged Pion Multiplicities in SIDIS Electroproduction

The experiments E12-09-002 and E12-09-017, which were completed in 2019 at Jefferson Lab Hall C, measured semi-inclusive charged pion electroproduction from hydrogen and deuterium. Our aim is to quantify charge symmetry violation (CSV) in valence quark distributions and also study the transverse momentum dependence of semi-inclusive pion production. In this talk, we will present some preliminary results on charged pion multiplicities and provide updates on the current analysis.
