Models for compound particles

Some versions of the Zachariasen model are used to describe mesons as bound particles. The resulting coupling constants are discussed and the resonances associated with the bound state through Levinson’s theorem are calculated.
Si usano alcune versioni del modello di Zachariasen per descrivere i mesoni come particelle legate. Si discutono le costanti di accoppiamento che ne risultano e si calcolano con il teorema di Levinson le risonanze associate allo stato legato.
