Gauge-invariant meson photoproduction with extended nucleons

Nuclear Theory 2007-05-23 v1

Abstract

The general gauge-invariant photoproduction formalism given by Haberzettl is applied to kaon photoproduction off the nucleon at the tree level, with form factors describing composite nucleons. Numerical results show that this gauge-invariance procedure, when compared to Ohta's, leads to a much improved description of experimental data. Predictions for the new Bonn SAPHIR data for p(γ,K+)Λp(\gamma,K^+)\Lambda are given.
