Baryon-baryon interactions and unitary symmetry

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

The baryon-baryon interactions are studied by making use of the octet version of the unitary symmetry model. The bound state Ξ−n in the1S0 state is predicted provided that the symmetry is not violated seriously. The Ξ-n → Σ−Σ0 process occurs only through the space-spin svmmetric state. A method to treat the symmetry violation in the lowenergy scattering is discussed.

Riassunto

Si studiano le interazioni barione-barione facendo uso della versione di ottetto del modello di simmetria unitaria. Si predice lo stato legato−n nello stato1S0, purchè non si violi in modo serio la simmetria. Il processo−n → Σ−Σ0 si veriflca solo tramite lo stato simmetrico dello spazio degli spin. Si discute un metodo per trattare la violazione della simmetria nello scattering di bassa energia.
