Description
The quark-gluon dynamics manifests itself in a set of non-perturbative functions describing all possible spin-spin and spin-orbit correlations defining azimuthal modulations in hard scattering processes. Production of correlated hadron pairs in current, as well as target fragmentation regions, plays an increasingly important role in the interpretation of pion electroproduction data in general, and hadronization process of quarks, in particular. More significant, than originally anticipated, fraction of pions and kaons coming from correlated di-hadrons, indicated by recent measurements at JLab, and supported by various realistic models describing the hadronization process, may have a significant impact on various aspects of data analysis, including the modeling, composition, and interpretation of semi-inclusive DIS data, as well as calculations of radiative corrections.
In this contribution, we will present ongoing studies, and some near term, as well as long term, future measurements related to studies of non-perturbative QCD effects at Jefferson Lab.
