Chiral constraints on the isoscalar electromagnetic spectral functions of the nucleon from leading order vector meson couplings
Using baryon chiral perturbation theory including vector mesons, we analyze various continuum contributions to the isoscalar electromagnetic spectral functions of the nucleon induced by the leading order couplings. Keywords: Electromagnetic form factors, Baryon chiral perturbation theory
