Title: A model for two-pion photoproduction amplitudes

A model for two-pion photoproduction amplitudes The authors present a brief discussion of the general form of the amplitude that describes the two-pion photoproduction process. They outline an effective Lagrangian method that they are using to calculate this amplitude, and comment briefly on a few aspects of the calculation.
