Width of exotics from QCD sum rules : tetraquarks or molecules?
Su Houng Lee, Kenji Morita, Marina Nielsen
We investigate the widths of the recently observed charmonium like resonances X(3872), Z(4430) and Z_2(4250) using QCD sum rules. Extending previous analyses regarding these states…
QCD sum rules study of the meson Z^+(4430)
Su Houng Lee, Antonio Mihara, Fernando S. Navarra +1
We use QCD sum rules to study the recently observed meson , considered as a molecule with . We consider the contributions of condensates up to dime…
Final state hadronic interactions and non-resonant decays
I. Bediaga, D. R. Boito, G. Guerrer +2
We evaluate the non-resonant decay amplitude of the process using an approach based on final state hadronic interactions described in terms of meson exchang…
QCD sum rules study of Ξ_c and Ξ_b baryons
Francisco O. Durães, Marina Nielsen
We use QCD sum rules to study the masses of the baryons and . We work with a current where the strange and the light quarks are in a relative spin zero, at leading order…
Do the QCD sum rules support four-quark states?
R. D. Matheus, F. S. Navarra, M. Nielsen +1
We test the validity of the QCD sum rules applied to the light scalar mesons, the charmed mesons and , and the X(3872) axial meson, considered as tetr…
QCD sum rules study of mesons
Fernando S. Navarra, Marina Nielsen, Su Houng Lee
We use QCD sum rules to study the possible existence of mesons, assumed to be a state with . For definiteness, we work with a current with an axial…
