Couplings of the eta and eta' Mesons to the Nucleon
N. F. Nasrallah
Abstract
The couplings of the eta and eta' mesons to the nucleon are obtained from the UA(1) Goldberger-Treiman relation. The chiral symmetry breaking corrections are very large and bring the calculated values of the coupling constants GetaNN and Geta'NN close to values obtained from potential models.
