Query: Low energy analysis of the nucleon electromagnetic form factors   We analyze the electromagnetic form factors of the nucleon to fourth order in
relativistic baryon chiral perturbation theory. We employ the recently proposed
infrared regularization scheme and show that the convergence of the chiral
expansion is improved as compared to the heavy fermion approach. We also
discuss the inclusion of vector mesons and obtain an accurate description of
all four nucleon form factors for momentum transfer squared up to Q^2 \simeq
0.4 GeV^2.
