Regge behaviour within the Bethe-Salpeter approach
Stanislav Kubrak, Christian S Fischer, Richard Williams
We present a calculation of the spectrum of light and heavy quark bound states in the rainbow-ladder truncation of Dyson-Schwinger/Bethe-Salpeter equations. By extending the formal…
Spectra of heavy mesons in the Bethe-Salpeter approach
Christian S. Fischer, Stanislav Kubrak, Richard Williams
We present a calculation of the spectrum of charmonia, bottomonia and B_c-meson states with `ordinary' and exotic quantum numbers. We discuss the merits and limitations of a rainbo…
Mass spectra and Regge trajectories of light mesons in the Bethe-Salpeter approach
Christian S. Fischer, Stanislav Kubrak, Richard Williams
We extend the calculation of relativistic bound-states of a fermion anti-fermion pair in the Bethe-Salpeter formalism to the case of total angular momentum . Together with res…
Beyond Rainbow-Ladder in a covariant three-body Bethe-Salpeter approach: Baryons
Hèlios Sanchis-Alepuz, Stanislav D. Kubrak, Christian S. Fischer
We report on recent results of a calculation of the nucleon and delta masses in a covariant bound-state approach, where to the simple rainbow-ladder gluon-exchange interaction kern…
Pion cloud effects on baryon masses
Helios Sanchis-Alepuz, Christian S. Fischer, Stanislav Kubrak
In this work we explore the effect of pion cloud contributions to the mass of the nucleon and the delta baryon. To this end we solve a coupled system of Dyson-Schwinger equations f…
The role of pions as virtual constituents of light bound states
Walter Heupel, Stanislav Kubrak, Gernot Eichmann +1
We summarize recent results for the spectrum and properties of light pseudoscalar and scalar hadrons in a functional approach to QCD using Dyson-Schwinger and Bethe-Salpeter equati…
