Summary

A new quantum number is introduced which leads to selection rules concerning transitions between states with heavy particle number = 0. They are applied to the system nucleon-antinucleon; it is also shown that they can be extended to include the conservation of strangeness.

Riassunto

Si introduce un nuovo numero quanticoG che porta a regole di selezione riguardanti le transizioni fra stati con un numeroN di particelle pesanti nullo. Tali regole sono poi applicate al sistema nucleone-antinucleone e viene anche mostrato che esse possono essere estese in modo da comprendere la conservazione della « stranezza »S.
