Structure of meson-baryon interaction vertices
Nov, 2008Citations per year
Abstract: (arXiv)
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.- 21.30.Fe
