3-Dimensional Adaptive Unstructured Tessellated Look-up Tables for the Approximation of Compton Form Factors

Charles Hyde, Mitch Kerver, Christos Tsolakis +8

We describe an iterative algorithm to construct an unstructured tessellation of simplices (irregular tetrahedra in 3-dimensions) to approximate an arbitrary function to a desired p…

Pion transverse charge density from $e^{+}$ $e^{-}$ annihilation data and logarithmic dispersion relations

Enrique Ruiz Arriola, Pablo Sanchez-Puertas, Christian Weiss

The transverse charge density of the pion is extracted from a dispersive analysis of the $e^{+} e^{-} \to π^{+} π^{-}$ exclusive annihilation data. A logarithmic dispersion relation…

Exploring Baryon Resonances with Transition Generalized Parton Distributions: Status and Perspectives

Stefan Diehl, Kyungseon Joo, Kirill Semenov-Tian-Shansky +21

QCD gives rise to a rich spectrum of excited baryon states. Understanding their internal structure is important for many areas of nuclear physics, such as nuclear forces, dense mat…
