Re-analysis of the nucleon space- and time-like electromagnetic form   factors in a two-component model
  Recent experimental data on space-like and time-like form factors of the nucleon are analyzed in terms of a two-component model with a quark-like intrinsic three-quark structure and quark-antiquark pairs.
