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…
Chiral-symmetry breaking and pion structure in the Covariant Spectator Theory
Elmar P. Biernat, M. T. Peña, Franz Gross +2
We introduce a covariant approach in Minkowski space for the description of quarks and mesons that exhibits both chiral-symmetry breaking and confinement. In a simple model for the…
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…
Chiral symmetry and pi-pi scattering in the Covariant Spectator Theory
Elmar P. Biernat, M. T. Peña, J. E. Ribeiro +2
The pi-pi scattering amplitude calculated with a model for the quark-antiquark interaction in the framework of the Covariant Spectator Theory (CST) is shown to satisfy the Adler ze…
Electromagnetic rho-meson form factors in point-form relativistic quantum mechanics
Elmar P. Biernat, Wolfgang Schweiger
The relativistic point-form formalism that we proposed for the study of the electroweak structure of few-body bound states is applied to calculate the elastic form factors of spin-…
