The $D_{s0}^*(2317)^+$ decay to $D_s^+\pi^0$ and $D_s^{*+}\gamma$
Abstract
We study the strong decay of to considering the coupled channels of and within a picture for the interaction based on the local hidden gauge approach. We also address the problem of the radiative decay to , using the same information obtained from the molecular picture. We obtain a strong width of the of about from coupled channels interaction and a radiative decay of about . We also show that the extra consideration of mixing can double the strong decay width to values around . The anomalous terms for the radiative decay are considered for the first time, but they are found negligible. We make a thorough discussion of this and other results to the light of the recent measurement of Belle for the ratio of these two decay modes, and make a call for the precise measurement of the two decay widths independently to clarify the present situation concerning the nature of the state.
