    "abstract": "By means of a coupled channel non-perturbative unitary approach, it is\npossible to extend the strong constrains of Chiral Perturbation Theory to\nhigher energies. In particular, it is possible to reproduce the lowest lying\nresonances in meson-meson scattering up to 1.2 GeV using the parameters of the\nO(p^2) and O(p^4) Chiral Lagrangian. The meson baryon sector can also be\ntackled along similar lines. We report on an update of these results showing\nsome examples of photon induced reactions where the techniques have been\nrecently applied.",
