Abstract
We have identified the first-order mixing amplitude of πNN process described by the hadron model with the second-order mixing amplitude of the same process described by the quark model. Then the expression for the coupling constant fπ of the πNN vertex with different quark wave functions and gluon propagators in different approximations has been derived. The calculation results of fπ have been compared with experimental data.
