Kinematical classification of two-pion production on the nucleon
arXiv:nucl-th/0304072
Abstract
We give a full kinematical classification of all the tree-level two-pion photoproduction processes on the nucleon, which consists of seventeen diagrams. It suggests a method of analysis of two-pion data with little model bias.
