Twist-3 Generalized Parton Distributions may provide an alternative source of information on quark orbital angular momentum. Additionally, twist-3 GPDs embody information on the spatial distribution of quark-gluon correlations and thus provide information about the transverse position dependence of forces that act on the active quark in a DIS experiment. We discuss both the connection between...

A wealth of information on the structure of matter lies in the correlations between the momentum and spatial distributions of the fundamental constituents of matter: quarks and gluons. These correlations are accessible via the study of generalized parton distributions (GPDs). The deeply-virtual Compton scattering (DVCS) is the preferred probe of GPDs and has been used to study the proton in a...

We suggest that generalized parton distributions can be probed in charged current meson production process, $ep\to \nu_e\pi^{-}p$. In contrast to pion photoproduction, this process is sensitive to the unpolarized GPDs $H,E$, and for this reason has a very small contamination by higher twist and Bethe-Heitler type contributions. Since all produced hadrons are charged, we expect that the...

The axial charge of the nucleon remains a quantity of phenomenological importance as it relates to nuclear beta decay and the degree of chiral symmetry breaking in QCD. Defined simply as the axial vector form factor at zero momentum transfer, the axial charge of the nucleon has long been a benchmark calculation in Lattice Field Theory. The bulk of Lattice determinations of the nucleon axial...

The non perturbative nature of QCD at low energies poses a challenge in
obtaining the properties of hadrons. LQCD has proven to be a useful tool for studying the structure of states that are stable under the strong interactions, which are a small fraction of the states present in QCD. In this talk, I will present efforts to study the structure of the majority of QCD states, which are either...
