Gravitational form factors of the proton from near-threshold vector meson photoproduction
Xiao-Yun Wang, Fancong Zeng, Jiyuan Zhang
We embark on a systematical analysis of the quark and gluon gravitational form factors (GFFs) of the proton, by connecting energy-momentum tensor (EMT) and the near-threshold vecto…
Analysis of the contribution of the quantum anomaly energy to the proton mass
Xiao-Yun Wang, Jingxuan Bu, Fancong Zeng
Inspired by the recent Hall C and GlueX measurements of photoproduction, a systematic analysis of the contribution of quantum anomalous energy (QAE) to the proton mass is car…
Gluon gravitational form factors of protons from charmonium photoproduction
Xiao-Yun Wang, Fancong Zeng, Quanjin Wang
Inspired by the recent near-threshold photoproduction measurements, we discuss gluon gravitational form factors (GFFs) and internal properties of the proton. This work presen…
First extraction of the proton mass radius and scattering length from photoproduction
Xiao-Yun Wang, Fancong Zeng, Quanjin Wang +1
As it involves the lightest physical states excited from the vacuum by the vector quark current, near-threshold photoproduction is considered a possible way to research the p…
