Structure of meson-baryon interaction vertices
arXiv:0811.0277 · doi:10.1103/PhysRevLett.102.132002
Abstract
We present a microscopic derivation of the form factors of strong-interaction piNN and piNDelta vertices within a relativistic constituent quark model. The results are compared with form factors from phenomenological meson-baryon models and recent lattice QCD calculations. We give an analytical representation of the vertex form factors suitable for applications in further studies of hadron reactions.
