Electromagnetic form factors of the nucleon in a relativistic quark pair creation model

We study the effects of the |qqqqq̄〉component of the hadronic wave function on the description of the electromagnetic structure of the nucleon. Starting with a 3qbaryonic wave function which describes the baryonic and mesonic low-energy spectrum, the extra qq̄pair is generated through a relativistic version of the 3P0model. 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 Q2dependence of the electromagnetic form factors at low Q2.
