Partial Wave Analysis Method in FDC

The FDC-PWA is a project to generate all the thing needed for partial wave analysis. It includes the following parts as:
Step 1: To construct effective strong interaction model for an input list of hadrons with quantum numbers.
Step 2: To generate Feynman diagram, Fortran source for cross section calculation and partial wave analysis for a given decay process based on the model from step 1.
This project was started by Jian-Xiong Wang, Bing-Song Zou and Yu-Can Zhu on 1998. The First version FDC-PWA was released for BES experiment physicist on 2000. There have been many new developments and improvements since then.

The newest version is FDC-PWA3.2.

The fdc-PWA_tutorial

The big model in J/psi energy range: there are about 400 hadron in the input list file and 30000 effective interaction vertices are generated by using FDC-PWA.

The Phenomenology Model for strong interaction in J/psi energy range

There are all the 2,3,4 final states processes which were searched and generated by using FDC-PWA. User can download the effective interaction model and process for each decay channel in the following link.
