Summary

The Schrödinger-like relativistic equation for bound states of the two-fermion system is considered. The general properties of solutions and spectra of such equations are derived. The equation is applied for a description of the$$q - \bar q$$ system with arbitrary spin. Using the square-well potential and two ways of symmetry breaking, the equation obtained for the$$q - \bar q$$ system is solved for pseudoscalar-octet mesons.

Riassunto

Si considera l’equazione relativistica del tipo di Schrödinger per stati del sistema di due fermioni. Si ricavano le proprietà generali delle soluzioni, e degli spettri di tali equazioni. Si usa l’equazione per descrivere sistemi$$q - \bar q$$ con spin arbitrario. Col potenziale di buca quadrata e con due tipi di rottura della simmetria si risolve l’equazione ottenuta per il sistema$$q - \bar q$$ per mesoni di ottetto pseudoscalare.

Резюме

Рассматривается релятивистское уравнение, типа уравнения Шредингера, для связанных состояний двух-фермионной системы. Выводятся общие свойства решений и спектров таких уравнений. Это уравнение используется для описания системы$$q - \bar q$$ с произвольным спином. Используя ступенчатый потенциал и два способа нарушения симметрии, полученное уравнение для системы$$q - \bar q$$ решается для псевдоскалярного октета мезонов.
