The electric dipole moment of elementary particles

  • R. L. Garwin
  • L. M. Lederman


The detection of electric dipole moments (EDM) of elementary particles is discussed and a new limit to the size of the electron EDM is presented (≲e · 1.5 · 10−15 cm). This result is used in a discussion of recent observations of positronium annihilation.


Si discute la rivelazione dei momenti di dipolo elettrico (EDM) delle particelle elementari e si ottiene un nuovo limite della grandezza dell’EDM dell’elettrone (≲e · 1.5 · 10−15 cm). Si usa tale risultato nella discussione di recenti osservazioni dell’annichilamento del positonio.

    W. Paul however notes that a second order effect may be observed in a strong electric field gradient. In this case the resultant electric field is proportional to the EDM times the field gradient.Google Scholar
