Running Coupling and Running Quark Mass Effects on the Elastic Form Factors of Nucleons

Bao-Yi Yang, Hui-Hua Zhong, Muyang Chen

We study the elastic electric and magnetic form factors of the proton, neutron and the charged roper resonance ($G_E^p$, $G_M^p$, $G_E^n$, $G_M^n$, $G_E^R$ and $G_M^R$) systematica…
