- The J=ÃDD¤ Vertex F. S. Navarra R. Silva Rodrigues da R.D. Matheus M. Nielsen Física, Astronomía y Matemáticas We employ QCD sum rules to calculate the J=ÃDD¤ form factors and coupling constant by studying the threepointJ=ÃD¤D correlation function. We find that the momentum dependence of the form factor depends onthe off-shell meson. We get a value for the coupling which is in agreement with estimates based on constituentquark model. 2004 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46400116 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.34
