EXACT-PROPAGATOR INSTANTANEOUS BETHE SALPETER EQUATION FOR QUARK ANTIQUARK BOUND STATES
- Physics
- 2006
Recently an instantaneous approximation to the Bethe–Salpeter formalism for the analysis of bound states in quantum field theory has been proposed which retains, in contrast to the Salpeter equation,…
Hadronic decays of mesons and baryons in the Dyson-Schwinger approach
- Physics
- 2011
We study hadronic decays of mesons and baryons in the context of the Dyson-Schwinger equations of QCD. Starting from a well-established effective interaction in rainbow-ladder truncation, we…
MESON SPECTROSCOPY AND PROPERTIES USING DYSON-SCHWINGER EQUATIONS
- Physics
- 2006
We study pseudoscalar and scalar mesons using a practical and symmetry preserving truncation of QCD's Dyson-Schwinger equations. We investigate and compare properties of ground and radially excited…
Charming quasi-exotic open-flavor mesons
- Physics
- 2017
We discuss charmed mesons in the covariant Dyson-Schwinger-Bethe-Salpeter-equation approach. In particular we computed masses, leptonic decay constants, and an orbital-angular-momentum decomposition…
S- and D-wave vector charmonia
- Physics
- 2017
We revisit earlier calculations of leptonic decay constants of vector charmonia and present and illustrate our decomposition of the corresponding covariant Bethe-Salpeter amplitudes in terms of…
Quasi-exotic open-flavor mesons
- Physics
- 2016
Abstract.Meson states with exotic quantum numbers arise naturally in a covariant bound-state framework in QCD. We investigate the consequences of shifting quark masses such that the states are no…
Aspects of open-flavour mesons in a comprehensive DSBSE study
- Physics
- 2017
Abstract.Open-flavour meson studies are the necessary completion to any comprehensive investigation of quarkonia. We extend recent studies of quarkonia in the Dyson-Schwinger-Bethe-Salpeter equation…

An hallmark of present-day Dyson-Schwinger equation appli cations in hadron physics is the existence of a systematic and symmetry preser ving truncation scheme. This enables the proof of exact…
STUDY OF $p\bar{\Lambda}$ AND $p\bar{\Sigma}$ SYSTEMS IN CONSTITUENT QUARK MODELS
- Physics
- 2011
The $p\bar{\Lambda}$ systems with J = 0 and J = 1 are dynamically investigated within the framework of two constituent quark models: the chiral quark model and the quark delocalization color…

Dyson–Schwinger Equations: A Tool for Hadron Physics
- Physics
- 2003
Dyson–Schwinger equations furnish a Poincare covariant framework within which to study hadrons. A particular feature is the existence of a nonperturbative, symmetry preserving truncation that enables…
Chirally symmetric quark description of low-energy pi pi scattering

Weinberg’s theorem for π-π scattering, including the Adler zero at threshold in the chiral limit, is analyticall proved for microscopic quark models that preserve chiral symmetry. Implementing…
Facets of confinement and dynamical chiral symmetry breaking
- Physics

Abstract.The gap equation is a cornerstone in understanding dynamical chiral symmetry breaking and may also provide clues to confinement. A symmetry-preserving truncation of its kernel enables proofs…
Nonperturbative structure of the quark-gluon vertex
- Physics
- 2003
The complete tensor structure of the quark-gluon vertex in Landau gauge is determined at two kinematical points (`asymmetric' and `symmetric') from lattice QCD in the quenched approximation. The…
The Ground State q anti-q Mass Spectrum in QCD
- Physics
- 1983
We use a relativistic equation of the Bethe-Salpeter type for quark-antiquark bound states in QCD. Its kernel, determined by the gluon propagator, is split into a constant part and a correction. This…
Analysis of a quenched lattice-QCD dressed-quark propagator
- Physics

Quenched lattice-QCD data on the dressed-quark Schwinger function can be correlated with dressed-gluon data via a rainbow gap equation so long as that equation's kernel possesses enhancement at…
