Multi-Dimensional Studies of the ep->e’p’X reaction with CLAS12 at Jefferson Lab

ORAL

Abstract

Studies of the properties and the azimuthal distribution of hadrons produced in the Target Fragmentation Region serve as a test of our complete understanding of the different mechanisms in the SIDIS production of hadrons and provide additional information on the QCD dynamics that are not accessible with single hadron production in the Current Fragmentation Region. We present first studies of beam SSA for semi-inclusive protons (ep → e′p'X), produced in the TFR, that can be related to higher twist Fracture Functions describing the FLU structure function. Such measurements on target-fragmentation protons were performed with the CLAS12 detector in Hall B at Jefferson lab. The preliminary results presented in this talk spanned the run period of fall 2018.
