    "abstract": "After a revision of the main features of the structure of the Dirac electron\na plausible definition of elementary particle is stated. It is shown that this\ndefinition leads in the classical case to a picture which produces a very clear\ncorrespondence between the classical and quantum mechanical features of the\nelectron. It is analyzed how the classical spin structure and zitterbewegung\nare related to the classical variables that define the kinematical state of the\nparticle.",
