The electromagnetic form factors of the proton and the neutron in the timelike region are investigated. The electron-positron annihilation into antinucleon-nucleon ( ¯ NN ) pairs is treated in distorted wave Born approximation, taking into account the final-state interaction in the ¯ NN system. The latter is obtained by a Lippmann-Schwinger equation for ¯ NN potentials derived within SU(3) chiral effective field theory. By fitting to the phase shifts and (differential) cross sections, a high quality…

The structure around pp̄ threshold of J/ψ → γη′π+π−: A revised version

In this paper, we update the study of the structure around pp̄ threshold discovered in η′π+π− invariant mass spectra of the process of J/ψ → γη′π+π−. The NN̄ re-scattering is taken into account, and

Emergence of the periodic oscillatory modulation in time-like nucleon form factors

We have studied the oscillatory behavior exhibited in the timelike electromagnetic form factors of nucleons by considering the final-state interaction effect. This mechanism introduces the Jost
