Exotic states and their properties from large- QCD
Wolfgang Lucha, Dmitri Melikhov, Hagop Sazdjian
The analysis of two-ordinary-meson scattering amplitudes in the limit of a large number of the colour degrees of freedom of quantum chromodynamics, with suitably decrea…
Tetraquark and two-meson states at large
Wolfgang Lucha, Dmitri Melikhov, Hagop Sazdjian
Considering four-point correlation functions of color-singlet quark bilinears, we investigate, in the large- limit of QCD, the subleading diagrams that involve, in…
Decay Constants of the Heavy-Light Mesons and : Isospin Breaking
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
QCD sum rules are analytic predictions of hadron observables from quantum chromodynamics. In the so-called local-duality limit of their Borel-transformed form, all nonperturbative…
Narrow exotic tetraquark mesons in large- QCD
Wolfgang Lucha, Dmitri Melikhov, Hagop Sazdjian
Discussing four-point Green functions of bilinear quark currents in large- QCD, we formulate rigorous criteria for selecting diagrams appropriate for the analysis of potential…
