We use the most general form of the interpolating currents to calculate the corresponding strong coupling constants. It is obtained that the coupling associated to N*N pi vertex is strongly suppressed compared to those related to two other vertices. The strong coupling corresponding to N*N*pi is obtained to be roughly half of that of NN pi vertex. We compare the obtained results on N*N pi and NN pi vertices with the existing predictions of other theoretical studies as well as those extracted from the experimental data.eninfo:eu-repo/semantics/closedAccess[No Keyword Available]ArticleQ2Q252419WOS:00037497910000111
