Abstract |
We study the strong decay of Ds0*(2317)+ to Ds+pi 0 considering the coupled channels of D0K+,D+K0,Ds+eta and Ds+pi 0 within a picture for the interaction based on the local hidden gauge approach. We also address the problem of the radiative decay to Ds & lowast;+gamma, using the same information obtained from the molecular picture. We obtain a strong width of the Ds0*(2317)+ of about 77 keV from coupled channels interaction and a radiative decay of about 1.7 keV. We also show that the extra consideration of pi 0-eta mixing can double the strong decay width to values around 140 keV. 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 Ds0*(2317)+ state. |
