Query: Electromagnetic Form Factors of the Nucleon in a Relativistic Quark Pair
  Creation Model   We study the effects of the | qqq q\bar{q} > component of the hadronic wave
function on the description of the electromagnetic structure of the nucleon.
Starting with a qqq baryonic wave function which describes the baryonic and
mesonic low energy spectrum, the extra q\bar{q} pair is generated through a
relativistic version of the 3P_0 model. It is shown that this model leads to a
renormalization of the quark mass that allows one to construct a conserved
electromagnetic current. We conclude that these dynamical relativistic
corrections play an important role in reproducing the Q2 dependence of the
electromagnetic form factors at low Q^2.
