Simulated Calculation of Scattering Cross Section of Proton-Deuteron to Helium-Pion Chain Decay Using Chiral Perturbation Theory

In this research, the chiral perturbation theory and the mechanism of three-body forces, which are of great importance, are employed through simulations to investigate the chain interaction. In the following, important parameters such as scattering amplitude ratio, decay rate, and scattering cross section of this decay have been calculated. Due to the fact that in nuclear processes, accuracy up to the next to leading order (NLO) can reduce the error rate to a high extent, the calculations performed in this research have been done up to (NLO). The obtained results are highly consistent with the experimental results.
