Coupling constants of $D^{} D_{s} K$ and $D_{s}^{} D K$ processes

M. E. Bracco, A. Lozea, A. Cerqueira +2

We calculate the coupling constants of $D^{*} D_{s} K$ and $D_{s}^{*} D K$ vertices using the QCD sum rules technique. We compare results obtained in the limit of SU(4) symmetry and found that…

Investigating the tetraquark structure of the new mesons

M. Nielsen, F. S. Navarra, M. E. Bracco

Using the QCD sum rule approach we investigate the possible four-quark structure of the recently observed mesons $D_{s J}^{+} (2317)$ , firstly observed by BaBaR, X(3872), firstly obs…

M. E. Bracco, F. S. Navarra, M. Nielsen

This paper has been withdrawn by the authors. We have discovered an error in the evaluation of the diagram, which invalidates our conclusion.
