Strong couplings of negative and positive parity nucleons to the heavy baryons and mesons
2015
Physical Review D
The strong coupling form factors related to the strong vertices of the positive and negative parity nucleons with the heavy Λ_b[c][Σ_b[c]] baryons and heavy B^*[D^*] vector mesons are calculated using a three-point correlation function. Using the values of the form factors at Q^2=-m^2_meson we compute the strong coupling constants among the participating particles.
