Vector-meson - nucleon couplings at spacelike momentum transfer

This is the authors' abstract. We don't add key points for this paper.

We have analyzed the presently available experimental data on the electromagnetic form factors for the nucleon to obtain information on the vector-meson-nucleon couplings. We obtained a strong momentum dependence of both vector and tensor couplings at spacelike momentum transfers. In addition a strong momentum dependence is found for the ratio of tensor/vector couplings. This indicates a small tensor coupling at $t=0$, despite a large value at t=mV². The results depend critically on the measured ratio of Pauli/Dirac em-proton form factors. So further measurements on all t would be of great interest concerning our understanding of the nucleon structure.
