Quark-Gluon-Quark Contributions to Twist Three GPDs

Twist three Generalized Parton Distributions and Generalized Transverse Momentum Distributions are central to the description of partonic orbital angular momentum. We discuss the origin of the genuine twist three contribution, described by the quark gluon quark correlator, to the twist three Generalized Parton Distribution ${\tilde{E}}_{2T}$ and how it connects to calculations of the $k_T^2$ moments of the Generalized Transverse Momentum Distribution F₁₄.
