Proton rms-radii from low-q power expansions?

Abstract

Several recent publications claim that the proton charge {\em rms}-radius resulting from the analysis of electron scattering data restricted to {\em low} momentum transfer agrees with the radius determined from muonic hydrogen, in contrast to the radius resulting from analyses of the full (e,e) data set which is $0.04fm$ larger. Here we show why these publications erroneously arrive at the low radii.
