Abstract

We study the strong energy dependence of the proton electromagnetic form factors in the time-like region, taking into account the one-pion-exchange final-state interaction in a covariant way. This effect is quantified in terms of the corrected Dirac F 1 and Pauli F 2 form factors and in the commonly used electric G E and magnetic G M ones. Our results on the ratio |G E /G M depend only on the values of two free parameters and allow significant comparisons with the BaBar data.
