Separation of the Target and Current Fragmentation Regions In electron-proton SIDIS

The majority of SIDIS studies have focused on the analysis of hadron production in the current-fragmentation region, while hadrons produced in the target fragmentation region, formed under the participation of the spectator partons, have been largely unexplored until now. Large acceptance of the CLAS12 detector at Jefferson Lab, allows studies of semi-inclusive hadron production both in current and target fragmentation regions. First preliminary results involving protons detected in the target fragmentation by the CLAS collaboration will be presented. Prospects for measurements at CLAS12 and future measurements at an upgraded JLab22 will be discussed.
