Summary
The question of which kind of mass formulae [(mass)2 vs. (mass)-2] are correct for a multiplet of vector mesons is studied. It is shown that from a field-theoretic point of view, one does not have a clear a priori preference for either kind of formulae.
Riassunto
Si esamina quale tipo di formula di massa [(massa)2 o (massa)’2] sia Corretto per un multipletto di mesoni vettoriali. Si dimostra che dal punto di vista della teoria dei campi, non ci sono a priori nette preferenze per l’uno o laltro tipo di formula.
