The Dubna-Mainz-Taipei Dynamical Model for $\pi N$ Scattering and $\pi$ Electromagnetic Production

Abstract

Some of the featured results of the Dubna-Mainz-Taipei (DMT) dynamical model for $\pi N$ scattering and ${\pi }^0$ electromagnetic production are summarized. These include results for threshold ${\pi }^0$ production, deformation of $\Delta (1232)$, and the extracted properties of higher resonances below 2 GeV. The excellent agreement of DMT model's predictions with threshold ${\pi }^0$ production data, including the recent precision measurements from MAMI establishes results of DMT model as a benchmark for experimentalists and theorists in dealing with threshold pion production.
