Phase structure and observables at high densities from first principles QCD
Christian S. Fischer, Jan M. Pawlowski
We provide a short review of the progress made in the past decade with functional QCD in the description of the phase structure of QCD. We summarise the most important technical as…
Functional methods for hadron spectroscopy
Gernot Eichmann, Christian S. Fischer, Joshua Hoffer
We summarize recent results for four-quark states with hidden and open flavor obtained from a four-quark Bethe-Salpeter/Faddeev-Yakubowsky equation. The approach dynamically predic…
Axial-vector and scalar contributions to hadronic light-by-light scattering
Gernot Eichmann, Christian S. Fischer, Tim Haeuser +1
We present results for single axial-vector and scalar meson pole contributions to the hadronic light-by-light scattering (HLbL) part of the muon's anomalous magnetic moment. In the…
Structure of open-flavour four-quark states in the charm and bottom region
Joshua Hoffer, Gernot Eichmann, Christian S. Fischer
We present quantitative results for masses and the internal structure of four-quark states with two heavy quarks, i.e. with and $q,q' \in \{u…
Hidden-flavour four-quark states in the charm and bottom region
Joshua Hoffer, Gernot Eichmann, Christian S. Fischer
We discuss the spectrum and the internal composition of ground and excited four-quark states in the charm and bottom energy region. To this end we extend previous calculations with…
Space-like Electromagnetic Form Factors of Lambda- and Sigma-Baryons from Quark-Diquark Faddeev Equations
Langtian Liu, Christian S. Fischer
An important goal of ongoing and future experiments is to explore spectra and transition form factors of baryons with non-zero strangeness. Of particular interest is the transition…
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…
