The dual parametrization for gluon GPDs

Understand

We consider the application of the dual parametrization for the case of gluon GPDs in the nucleon.

• This provides opportunities for the more flexible modeling unpolarized gluon GPDs in a nucleon which in particular contain the invaluable information on the fraction of nucleon spin carried by gluons.
• We perform the generalization of Abel transform tomography approach for the case of gluons.
• We also discuss the skewness effect in the framework of the dual parametrization.
