Abstract

A brief overview of charm scalar resonances is given. It is demonstrated that experimental data on the D_s^*+gamma and D_s⁺pi⁰ decays of D_s0⁺(2317) favor its assignment to the I₃=0 component of iso-triplet four-quark mesons. The broad bump just below a large peak of the well-known D₂^* meson in the Dpi channel is also studied.
