New value of the proton charge root mean square radius

New value of the proton charge root mean square radius

The non-dipole behavior of GEp(Q2) in the space-like region with the zero around Q2=13GeV2 is found in a global analysis of all existing nucleon electromagnetic form factor data by means of a sophisticated analytic model of nucleon electromagnetic structure. From such behavior of GEp(Q2), the charge...

Description
Summary:The non-dipole behavior of GEp(Q2) in the space-like region with the zero around Q2=13GeV2 is found in a global analysis of all existing nucleon electromagnetic form factor data by means of a sophisticated analytic model of nucleon electromagnetic structure. From such behavior of GEp(Q2), the charge proton root mean square (rms) radius is compatible with the value obtained recently from spectroscopy of the muon hydrogen atom.
