Elastic differential cross section of ep scattering fitted via the differential cross section of eq scatterings with cloud-covering effects

The angular-averaged differential cross section (dcs) of the elastic electron-proton (ep) scattering, covering Q2<1.0 GeV2, was fitted via a combined modified eq-scatterings where q is a point particle. The modifications represent the cloud-covering effects to q. An energy-decaying ratio (edr) was derived by inspecting the generated dcsep from the form factor data gathered at Mainz Microtron (A1-Collaboration) and Continuous Electron Beam Accelerator Facility (Jefferson Laboratory) when compared to the dcseq with modified relativistic recoil factor. The diminishing cloud layer, edr, has a decay rate of -2.8 for the datasets under investigation. The formulated spin bare mass (SBM) and spin effective mass (SEM) fitting models use the bare and effective u and d-quark masses, respectively, while spin with other criteria bare mass (SCBM) and spin with other criteria effective mass (SCEM) integrate other considerations. Three comparison methods were used and all of them favor the models with other additional considerations. SCEM was the most favored model in general.
