We study the transverse charge and current densities in the periphery of the
nucleon where they are governed by universal chiral dynamics. The large
distance asymptotics of the densities are derived from the spectral functions
of the Dirac and Pauli form factors near the threshold at t=4M_pi2 obtained
from invariant chiral perturbation theory. In the equivalent light front
formulation, the peripheral densities arise from large size piN configurations
in the nucleonĮs light front wave function obtained from the chiral Lagrangian.
We compute the chiral component of the charge and current densities and
explain their order of magnitude in the chiral expansion. We also discuss the
role of pi Delta intermediate states in the large Nc limit and the heavy
baryon expansion of peripheral densities, and comment on progress extending an
analogous analysis concerning transverse densities from form factors of the
energy-momentum tensor and its connections with studies on GPDs.
