A unitary symmetry selection rule and its application to new resonances

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

A selection rule is formulated, which forbids the decay into two pseudoscalar mesons of all members of a unitary multiplet containing a neutral boson which is odd underCP. It is applied to the classification of resonances like thex and B which decay into pseudoscalar vector mesons. An additional rule forbids the decay into two pseudoscalar mesons of all members of a tenfold multiplet which has even parity.

Riassunto

Si formula una regola di selezione, che proibisce il decadimento in due mesoni pseudoscalari di tutti i membri di un multipletto unitario contenente un bosone neutro che è dispari rispetto aCP. Essa si applica alla classificazione di risonanze comex e B che decadono in mesoni pseudoscalari e vettoriali. Un’ulteriore regola proibisce il decadimento in due mesoni pseudoscalari di tutti i membri di un multipletto decuplo che ha parità pari.
