Nucleon–meson coupling constants and form factors in the quark model
Physics Letters B
We demonstrate the calculation of the coupling constants and form factors required by effective hadron lagrangians using the quark model. These relations follow from equating expressions for strong transition amplitudes in the two approaches. As examples we derive the NNm nucleon-meson coupling constants and form factors for m = pi, eta, eta', sigma, a_0, omega and rho, using harmonic oscillator quark model meson and baryon wavefunctions and the 3P0 decay model; this is a first step towardsdoi:10.1016/j.physletb.2006.05.084 fatcat:pyyhoibwfjcjnl7rswci4fslny
