On charm scalar resonances
Abstract
Description
A brief overview of charm scalar resonances is given. It is demonstrated that experimental data on the D_s^{*+}gamma and D_s^+pi^0 decays of D_{s0}^+(2317) favor its assignment to the I_3=0 component of iso-triplet four-quark mesons. The broad bump just below a large peak of the well-known D_2^* meson in the Dpi channel is also studied.
