Abstract
Abstract The couplings of the η and η ′ mesons to the nucleon are obtained from the U A ( 1 ) Goldberger–Treiman relation. The chiral symmetry breaking corrections are very large and bring the calculated values of the coupling constants G η N N and G η ′ N N close to values obtained from potential models.
