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…
Heavy and heavy-light mesons in the Covariant Spectator Theory
Alfred Stadler, Sofia Leitão, M. T. Peña +1
The masses and vertex functions of heavy and heavy-light mesons, described as quark-antiquark bound states, are calculated with the Covariant Spectator Theory (CST). We use a kerne…
Quark mass functions and pion structure in the Covariant Spectator Theory
E. P. Biernat, F. Gross, M. T. Peña +2
The Covariant Spectator Theory is applied to the description of quarks and the pion. The dressed quark mass function is calculated dynamically in Minkowski space and used in the ca…
Heavy and heavy-light mesons and the Lorentz structure of the quark-antiquark interaction
Sofia Leitão, Alfred Stadler, M. T. Peña +1
We solve a Minkowski-space integral equation, derived in the Covariant Spectator Theory, for quark-antiquark bound states describing heavy and heavy-light mesons. The equation's ke…
Covariant spectator theory of quark-antiquark bound states: Mass spectra and vertex functions of heavy and heavy-light mesons
Sofia Leitão, Alfred Stadler, M. T. Peña +1
We use the covariant spectator theory with an effective quark-antiquark interaction, containing Lorentz scalar, pseudoscalar, and vector contributions, to calculate the masses and…
Comparison of two Minkowski-space approaches to heavy quarkonia
Sofia Leitão, Yang Li, Pieter Maris +4
In this work we compare mass spectra and decay constants obtained from two recent, independent, and fully relativistic approaches to the quarkonium bound-state problem: the Hamilto…
