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…
Diquark-Antidiquark with open charm in QCD sum rules
M. Nielsen, R. D. Matheus, F. S. Navarra +2
Using the QCD sum rule approach we investigate the possible four-quark structure of the recently observed charmed scalar mesons (BELLE) and (FOCUS…
Disentangling two- and four-quark state pictures of the charmed scalar mesons
M. E. Bracco, A. Lozea, R. D. Matheus +2
We suggest that the recently observed charmed scalar mesons (BELLE) and (FOCUS) are considered as different resonances. Using the QCD sum rule app…
D and rho Mesons: Who resolves whom?
M. E. Bracco, M. Chiapparini, A. Lozea +2
The DDrho form factor is evaluated in a QCD sum rule calculation for both D and rho off-shell mesons. We study the double Borel sum rule for the three point function of two pseudos…
