Two pion photoproduction on nucleons and nuclei in the rho and sigma regions

E. Oset, L. Roca, M. J. Vicente Vacas +1

In this talk we report on two physical processes, the photoproduction of $\rho$ mesons in nuclei and the ${\pi }^0{\pi }^0$ photoproduction in nuclei at low energies. In the first case the aim…
