What is the difference between the "real" particle electron (for instance) and the spinor field of electron? I mean, which means that the electron have been described by a spinor field?My question is based upon a phrase from Geroch's book [ http://strangebeautiful.com/other-texts/geroch-qft-lectures.pdf ]

Particles with half-integer spin (electrons, neutrinos, etc.) are described by mathematical objects called spinor fields

    $\begingroup$ But my question deals specific with Spinor mathematics. Although could be a duplicate. $\endgroup$ – M.N.Raia Mar 4 '19 at 2:57

    $\begingroup$ The conceptual distinction between quantum fields and their particle-like quanta is the same regardless of spin. $\endgroup$ – G. Smith Mar 4 '19 at 4:01
