Microscopic model of the timelike electromagnetic form factor of the nucleon.
A microscopic model of the electromagnetic form factor of the nucleon is developed in a hadronic framework, including pions, nucleons and the ∆-resonance explicitly. The space like on-shell form factors are reproduced and predictions for the half off-shell dependence are made. The impact of this off-shell dependence in the time like sector (q 2 < 1 GeV 2 , thus including the region of vector me...

The fourth dimension of the nucleon structure: spacetime analysis of the timelike electromagnetic proton form factors
As well known, spacelike proton form factors expressed in the Breit frame may be interpreted as the Fourier transform of static space distributions of electric charge and current. In particular, the electric form factor is simply the Fourier transform of the charge distribution F (q) = ∫ e ρ(r)dr. We don’t have an intuitive interpretation of the same level of simplicity for the proton timelike ...
