Electromagnetic decays of the neutral pion

We propose a simple classical electrodynamics model in which a Lorentz pseudoscalar field and a Dirac field are present in the general Lagrangian of the system. The model is constructed by allowing explicit violation of chiral symmetry. This approach is intended to predict possible electromagnetic decays of the neutral pion in effective terms.

K Matrix

The energy dependence of the electric dipole amplitude, the total and differential cross-sections of the photoproduction of neutral pions off protons near threshold is given. The amplitude of process is a sum of the LET prediction and the additional term connected with the chiral symmetry breaking interaction. The simple K-matrix calculations are used to estimate the change in the electric dipole amplitude and the total and differential cross-sections between π0p and π+n thresholds.
