Goldstonic pseudoscalar mesons in Bethe-Salpeter-inspired setting
Wolfgang Lucha, Franz F. Schoberl
For a two-particle bound-state equation closer to its Bethe-Salpeter origins than Salpeter's equation, with effective-interaction kernel deliberately forged such as to ensure, in t…
Isospin Breaking in Heavy-Meson Decay Constants
Wolfgang Lucha, Dmitri Melikhov, Silvano Simula
Evaluation of Borelized QCD sum rules in the so-called local-duality limit of infinitely large Borel mass parameter provides an alternate route for extraction of the dependence of…
Narrow-width tetraquarks in large- QCD
Wolfgang Lucha, Dmitri Melikhov, Hagop Sazdjian
The properties of possibly existing tetraquarks are studied in the large- limit of QCD by means of four-point correlation functions of meson currents.The necessi…
Constraints from the Expansion on Properties of Exotic Tetraquark Mesons
Wolfgang Lucha, Dmitri Melikhov, Hagop Sazdjian
Scrutinizing the scattering of ordinary mesons in the limiting case of the number of colour degrees of freedom of quantum chromodynamics approaching infinity, we formul…
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…
Instantaneous Bethe-Salpeter Look at the Lightest Pseudoscalar Mesons
Wolfgang Lucha, Franz F. Schoberl
Within our description of Goldstone-type pseudoscalar mesons as almost massless bound states of quark and antiquark by a three-dimensional bound-state equation of Bethe-Salpeter or…
