Parton Distribution Functions from Large Momentum Expansion of Current-Current Correlators
Jialu Zhang, Xiangdong Ji, Andreas Schäfer +2
The universality of the large momentum expansion allows computing parton distribution functions (PDFs) starting from any Euclidean correlator with appropriate large momentum Fourie…
GUMP1.0 -- First global extraction of generalized parton distributions from experiment and lattice data with NLO accuracy
Yuxun Guo, Fatma P. Aslan, Xiangdong Ji +1
We report the first global extraction of generalized parton distributions (GPDs), GUMP1.0, by combining deeply virtual Compton scattering and -meson production data from Jeffer…
Small- gluon GPD constrained from deeply virtual production and gluon PDF through universal-moment parameterization
Yuxun Guo, Xiangdong Ji, M. Gabriel Santiago +2
We phenomenologically constrain the small- and small- gluon generalized parton distributions (GPDs) with the deeply virtual production (DVP) in the framework of…
On convergence properties of GPD expansion through Mellin/conformal moments and orthogonal polynomials
Hao-Cheng Zhang, Xiangdong Ji
We examine convergence properties of reconstructing the generalized parton distributions (GPDs) through the universal moment parameterization (GUMP). We provide a heuristic explana…
