The vertex in QCD Sum Rules: form factors and coupling constant
A. Cerqueira, B. Osório Rodrigues, M. E. Bracco +1
In this work we study the meson vertex using the QCD sum rules. We compute the three point correlation functions for the three cases of different off-shell mesons. The fo…

B. Osório Rodrigues, M. E. Bracco, C. M. Zanetti
We use the QCD sum rules for the three point correlation functions to compute the strong coupling constants of the meson vertices and . We consider pertu…

The strong coupling constant from QCD Sum Rules
Bruno Osório Rodrigues, Mirian Enriqueta Bracco, Marcelo Chiapparini
The coupling constant of the meson vertex is calculated using the three point correlation function within the QCD Sum Rule formalism. We have considered alternately me…
Obtaining the strong coupling constants g_{J/ψD_s D_s} and g_{ϕD_s D_s} from QCD Sum Rules
M. E. Bracco, M. Chiapparini, B. Osório Rodrigues
The form factors and coupling constants of the meson vertices J/ψD_s D_s and ϕD_s D_s were calculated using three point correlation functions within the QCD Sum Rules formalism. We…
