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…

The form factors and the coupling constant of the and vertices are calculated using the QCD sum rules method. Three point correlation functions are compute…
vertex from QCD sum rules
A. Cerqueira, B. Osório Rodrigues, M. E. Bracco
The form factors and the coupling constant of the vertex are calculated using the QCD sum rules method. Three point correlation functions are computed considering both…
Coupling constants of and processes
M. E. Bracco, A. Lozea, A. Cerqueira +2
We calculate the coupling constants of and vertices using the QCD sum rules technique. We compare results obtained in the limit of SU(4) symmetry and found that…
