Generalized parton distributions: Theory meets experiment
Yuxun Guo, Xiangdong Ji, Yao Ji +1
Over the past three decades, generalized parton distributions (GPDs) have emerged as one of the most active and important areas of research in nucleon structure and quantum chromod…
Three-qubit entanglement in the Bethe-Heitler process
Haotian Cao, Yuxun Guo, Yoshitaka Hatta +1
The familiar Bethe-Heitler process on the proton target is transformed into a laboratory for studying multiparticle entanglement. We discuss how bipartite and genuin…
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 Jeffers…
