Summary
The effective action for the 2-dimensionalCP N−1 model with quarks is explicity calculated in the low-energy limit, its 1/N expansion and properties under chiral symmetry are discussed.
Riassunto
Si calcola l'azione efficace, nel limite di bassa energia, per il modelloCP N−1 bidimensionale con quark. Se ne discute inoltre lo sviluppo 1/N e le proprietà nella simmetria chirale.
Резюме
В пределе низких энергий в явном виде бычисляется эффективное действие для двумернойCP N−1 модели с кварками. Обсуждаются 1/N разложение и свойство модели относительно кираьной симметрии.
