Phys. Rev. C 69, 055204 (2004) [5 pages]Structure of the nucleon from electromagnetic timelike form factorsReceived 15 December 2003; published 21 May 2004 Recent experimental data on spacelike and timelike form factors of the nucleon are analyzed in terms of a model with an intrinsic structure and a meson cloud. The calculations are in perfect agreement with spacelike proton data, but deviate drastically from spacelike neutron data at Q2>1 (GeV∕c)2. We suggest that timelike data be used to understand this discrepancy. Analysis of timelike data shows excellent agreement with both proton and neutron data in the entire range of measured q2=−Q2, 3.52⩽q2⩽15 (GeV∕c)2 values. © 2004 The American Physical Society URL:
