Model comparison of Delta and Omega masses in a covariant Faddeev approach
Helios Sanchis-Alepuz, Reinhard Alkofer, Gernot Eichmann +1
We compute the vector-meson, nucleon and delta/omega-baryon masses and their evolution with the current-quark mass using a covariant generalized Bethe-Salpeter equation approach. T…
A first estimate of triply heavy baryon masses from the pNRQCD perturbative static potential
Felipe J. Llanes-Estrada, Olga I. Pavlova, Richard Williams
Within pNRQCD we compute the masses of spin-averaged triply heavy baryons using the now-available NNLO pNRQCD potentials and three-body variational approach. We focus in particular…
Hadronic contribution to the muon g-2: a Dyson-Schwinger perspective
Tobias Goecke, Christian S. Fischer, Richard Williams
We summarize our results for hadronic contributions to the anomalous magnetic moment of the muon (), the one from hadronic vacuum-polarisation (HVP) and the light-by-light sca…
Effects of Anisotropy in (2+1)-dimensional QED
J. A. Bonnet, C. S. Fischer, R. Williams
We summarize our results for the impact of anisotropic fermionic velocities in (2+1)-dimensional QED on the critical number of fermion flavors, N^c_f, and dynamical mass generation…
Leading-order calculation of hadronic contributions to the muon using the Dyson-Schwinger approach
Tobias Goecke, Christian S. Fischer, Richard Williams
We present a calculation of the hadronic vacuum polarization (HVP) tensor within the framework of Dyson--Schwinger equations. To this end we use a well-established phenomenological…
Effects of Anisotropy in QED3 from Dyson-Schwinger equations in a box
Jacqueline A. Bonnet, Christian S. Fischer, Richard Williams
We investigate the effect of anisotropies in the fermion velocities of 2+1 dimensional QED on the critical number N_f^c of fermions for dynamical mass generation. Our framework are…
