| Test of two new parameterizations of the Generalized Parton Distribution H
|
| C. Mezrag, H. Moutarde, F. Sabatié |
| In 2011 Radyushkin outlined the practical implementation of the One-Component
Double Distribution formalism in realistic Generalized Parton Distribution models. We
compare the One-Component Double Distribution framework to the standard one and
compute Deeply Virtual Compton Scattering observables for both. In particular the new
implementation is more flexible, offering a greater range of variation of the real and imaginary
parts of the associated Compton Form Factor while still allowing to recover results
similar to the classical approach. Moreover the polynomiality property is satisfied up to
the highest order. Although the comparison to experimental data may be improved, the
One-Component Double Distribution modeling is thus an attractive alternative |
