Unitary model for the $\gamma p\to \gamma {\pi }^{0}p$ reaction and the magnetic dipole moment of the ${\Delta }^{+}(1232)$

Radiative pion photoproduction in the $\Delta (1232)$ resonance region is studied with the aim to access the ${\Delta }^{+}(1232)$ magnetic dipole moment. We present a unitary model of the $γp \to…
