Baryon-baryon interactions and unitary symmetry



The baryon-baryon interactions are studied by making use of the octet version of the unitary symmetry model. The bound state Ξn in the1S0 state is predicted provided that the symmetry is not violated seriously. The Ξ-n → ΣΣ0 process occurs only through the space-spin svmmetric state. A method to treat the symmetry violation in the lowenergy scattering is discussed.


Si studiano le interazioni barione-barione facendo uso della versione di ottetto del modello di simmetria unitaria. Si predice lo stato legaton nello stato1S0, purchè non si violi in modo serio la simmetria. Il processon → ΣΣ0 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.
