    "abstract": "We study the photoproduction of scalar mesons close to the threshold of\nf_0(980) and a_0(980) using a unitary chiral model. Peaks for both resonances\nshow up in the invariant mass distributions of pairs of pseudoscalar mesons. A\ndiscussion is made on the photoproduction of these resonances in nuclei, which\ncan shed light on their nature, a subject of continuous debate.",
