Nonlocal properties of the neutrino

  • S. B. Berger


Fleming’s nonlocal center-of-energy position operator for massive, closed, relativistic systems is extended to the case of the (massless) Weyl neutrino. The nonlocal position operator derived in this new case is shown to be identical to corresponding operators introduced by me and also by Kalnay. Furthermore, I discuss a possible relationship between linear-momentum and angular-momentum operators in this special case.

Si estende l’operatore di posizione del centro di energia non locale di Fleming per sistemi massivi, chiusi, relativistici, al caso del neutrino (privo di massa) di Weyl. L’operatore di posizione non locale derivato in questo caso è mostrato essere identico ai corrispondenti operatori introdotti da me ed anche da Kalnay. Inoltre, si discute una possibile reazione tra gli operatori d’impulso lineare ed angolare in questo caso speciale.
