Quark mass functions in Minkowski space
Elmar P. Biernat, Franz Gross, M. T. Peña +1
Using the Covariant Spectator Theory (CST), we calculate the dressed quark mass function and wave-function renormalization for the five quark flavors from up/down to bottom in both…
Heavy and heavy-light mesons with arbitrary spin and parity in the Covariant Spectator Theory
Alfred Stadler, Elmar P. Biernat
This work generalizes the one-channel Covariant Spectator Theory (CST) formalism to describe quark-antiquark mesons of arbitrary spin-parity . We also improve the quark-antiqu…
Heavy and heavy-light tensor and axial-tensor mesons in the Covariant Spectator Theory
Elmar P. Biernat, Alfred Stadler
We present the first calculation of tensor and axial-tensor mesons with total spin within the Covariant Spectator Theory. We employ a refined quark-antiquark interaction k…
Simple high-accuracy method for solving bound-state equations with the Cornell potential in momentum space
Alfred Stadler, Elmar P. Biernat, Vasco Valverde
The well-known Cornell quark-antiquark potential in momentum space contains singularities both in its one-gluon-exchange (OGE) and linear confining parts, which prevents a direct u…
Quark mass function from a one-gluon-exchange-type interaction in Minkowski space
Elmar P. Biernat, Franz Gross, M. T Peña +2
We present first results for the quark mass function in Minkowski space in both the spacelike and timelike regions calculated from the same quark-antiquark interaction kernel used…
Constituent-quark model with pionic contributions: electromagnetic transition
Ju-Hyun Jung, Wolfgang Schweiger, Elmar P. Biernat
We report on ongoing work to determine the pion-cloud contribution to the electromagnetic transition form factors. The starting point is an spin-flavor symm…
