Abstract

This thesis presents the evaluation of the relative contributions of various twist-3 quark-gluon correlation functions relevant to single transverse spin asymmetry (SSAs) in a quark-diquark model of the nucleons. The twist-3 quark-gluon correlation functions responsible for gluonic pole and fermionic pole contributions are calculated and compared. We find that at the leading nontrivial order, only gluonic pole contribution is finite and all others are zero for both scalar diquark and axial-vector diquark. We also evalute the symmetries of the these twist-3 quark-gluon correlation functions explicitely
