1. Chiral Odd GPDs.

Abstract

Nucleon spin structure, transversity and the tensor charge are of central importance to understanding the role of QCD in hadronic physics. A new approach to measuring orbital angular momenta of quarks in the proton via twist 3 GPDs is shown. The "flexible parametrization" of chiral even GPDs is reviewed and its transformation into the chiral odd sector is discussed. The resulting parametrization is applied to recent data on π0 and η electroproduction. [ABSTRACT FROM AUTHOR]

2. Beyond-Standard-Model Tensor Interaction and Hadron Phenomenology.

Author

Courtoy, Aurore, Baeßler, Stefan, González-Alonso, Martín, and Liuti, Simonetta

Subjects
*STANDARD model (Nuclear physics), *HADRON interactions, *QUANTUM chromodynamics, *HADRONIC atoms, *PARTONS
Abstract

We evaluate the impact of recent developments in hadron phenomenology on extracting possible fundamental tensor interactions beyond the standard model. We show that a novel class of observables, including the chiral-odd generalized parton distributions, and the transversity parton distribution function can contribute to the constraints on this quantity. Experimental extractions of the tensor hadronic matrix elements, if sufficiently precise, will provide a, sofar, absent testing ground for lattice QCD calculations. [ABSTRACT FROM AUTHOR]
