Abstract
In order to assess the relevance of chiral dynamics in the scalar sector we address two recent problems: radiative decay of the $Ï$, for which there are quite recent data from Frascati, and the modification of the $Ï$ properties in the nuclear medium seen through the $Ï^0 Ï^0$ photoproduction in nuclei.
