Jlab Proton Polarization Data in Aspect to Global Unitary and Analytic Model of Nucleon Electromagnetic Structure

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

It is demonstrated that new JLAB proton polarization data, which are in a rather strong disagreement with the proton electric form factor data in the space-like region obtained by Rosenbluth technique, are consistent with all known form factor properties, including also the QCD asymptotics, but they require an existence of a zero (i.e. a diffraction minimum) around tt=15 GeV2^2 of the proton electric form factor. The latter leads to a change of our knowledge about the charge distribution inside of the proton.
