${\pi }^0$-$\gamma$ mixing in the presence of a strong magnetic field

D. Gomez Dumm, S. Noguera, N. N. Scoccola

We analyze the mixing between the ${\pi }^0$ meson and the photon in the presence of a strong uniform magnetic field, in the context of a two-flavor Nambu-Jona-Lasinio model. It is show…
