Electromagnetic proton form factors in dual large-Nc QCD: An update

An updated determination is presented of the electric and magnetic form factors of the proton, in the framework of a dual-model realization of quantum chromodynamics (QCD) in the limit of an infinite number of colors. Very good agreement with data is obtained in the space-like region up to [Formula: see text]. In particular, the ratio [Formula: see text] is predicted in very good agreement with recoil polarization measurements from Jefferson Lab, up to [Formula: see text].

Proton Form Factors

Recently an experiment at Jefferson Lab has measured the proton form factor ratio, [Formula: see text], down to Q2 ~ 0.3 GeV 2 with unprecedented precision. Based on the results from this experiment, a re-analysis was carried out for the world data on proton form factors, and a new result was extracted for the proton charge radius. The new result is consistent with published CODATA results and is at odds with the new muonic hydrogen measurement at PSI. We present the results of the new measurement, as well as discuss an upcoming experiment to measure the form factor ratio down to even lower Q2.

Proton Form Factors

During the last three lustra nucleon form factors experiments have lived a golden age, full of interesting results, that likely will continue and culminate when new data will come from BESIII, SND, CMD3 and PANDA, in the time-like region and, Jefferson Lab and A1 in the space-like region. On the other hand, from theoretical point of view, mainly concerning the possibility of descriptions in all kinematical regions, no great breakthrough has been made.
