Likelihood of a zero in the proton elastic electric form factor

Peng Cheng, Zhao-Qian Yao, Daniele Binosi +1

Working with the $29$ available data on the ratio of proton electric and magnetic form factors, $μ_{p} G_{E}^{p} (Q^{2}) / G_{M}^{p} (Q^{2})$ , and independent of any model or theory of strong inter…

Baryon Spin and Emergent Hadron Mass

Peng Cheng

This thesis describes the use of Dyson-Schwinger equations (DSEs) to study baryon bound states in QCD. In this work, octet baryon axial form factors are calculated using a symmetry…

Contact interaction study of proton parton distributions

Yang Yu, Peng Cheng, Hui-Yu Xing +2

Using a symmetry-preserving formulation of a vector $\times$ vector contact interaction (SCI) and treating the proton as a quark + interacting-diquark bound state, whose structur…
