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…

Relativistic phenomenology of meson spectra with a covariant quark model in Minkowski space

Sofia Leitão, Alfred Stadler, M. T. Peña +1

In this work, we perform a covariant treatment of quark-antiquark systems. We calculate the spectra and wave functions using a formalism based on the Covariant Spectator Theory (CS…

Application of the Covariant Spectator Theory to the study of heavy and heavy-light mesons

Sofia Leitão, Alfred Stadler, M. T. Peña +1

As an application of the Covariant Spectator Theory (CST) we calculate the spectrum of heavy-light and heavy-heavy mesons using covariant versions of a linear confining potential,…

Covariant Spectator Theory of heavy-light and heavy mesons and the predictive power of covariant interaction kernels

Sofia Leitão, Alfred Stadler, M. T. Peña +1

The Covariant Spectator Theory (CST) is used to calculate the mass spectrum and vertex functions of heavy-light and heavy mesons in Minkowski space. The covariant kernel contains L…

Quarkonia and heavy-light mesons in a covariant quark model

Sofia Leitão, Alfred Stadler, M. T. Peña +1

Preliminary calculations using the Covariant Spectator Theory (CST) employed a scalar linear confining interaction and an additional constant vector potential to compute the mesoni…

A covariant constituent-quark formalism for mesons

S. Leitão, A. Stadler, M. T. Peña +1

Using the framework of the Covariant Spectator Theory (CST) [1] we are developing a covariant model formulated in Minkowski space to study mesonic structure and spectra. Treating m…

Linear confinement in momentum space: singularity-free bound-state equations

Sofia Leitão, Alfred Stadler, M. T. Peña +1

Relativistic equations of Bethe-Salpeter type for hadron structure are most conveniently formulated in momentum space. The presence of confining interactions causes complications b…

Singularity-free two-body equation with confining interactions in momentum space

Alfred Stadler, Sofia Leitão, M. T. Peña +1

We are developing a covariant model for all mesons that can be described as quark-antiquark bound states in the framework of the Covariant Spectator Theory (CST) in Minkowski space…
