- Coupling Constants of D*DsK and D*s DK Processes A. Cerqueira M. E. Bracco A. Lozéa M. Chiapparini M. Nielsen Física, Astronomía y Matemáticas Form Factors QCD Sum Rule Coupling constants We calculate the coupling constants of D∗DsK and D∗s DK vertices using the QCD sum rules technique. Wecompare our results with results obtained in the limit of SU(4) symmetry and we found that the symmetry isbroken at the order of 40%. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437119 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.1A Vol.37
