Extraction of the Parton Momentum-Fraction Dependence of Generalized Parton Distributions from Exclusive Photoproduction

Jian-Wei Qiu, Zhite Yu

The $x$ dependence of hadrons' generalized parton distributions (GPDs) $\mathcal{F}(x,\xi ,t)$ is the most difficult to extract from the existing known processes, while the $\xi$ and $t…
