A QCD sum rules calculation of the and form factors and strong coupling constants
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…
and vertices using QCD sum rules
A. Cerqueira, B. Osório Rodrigues, M. E. Bracco +1
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…
The B_{s0} meson and the B_{s0}B K coupling from QCD sum rules
M. E. Bracco, M. Nielsen
We evaluate the mass of the scalar meson and the coupling constant in the vertex in the framework of QCD sum rules. We consider the as a tetraquark s…
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…
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 , firstly observed by BaBaR, X(3872), firstly obs…
