Strong Two--Body Decays of Light Mesons
Ralf Ricken, Matthias Koll, Dirk Merten +1
In this paper, we present results on strong two-body decay widths of light mesons calculated in a covariant quark model. The model is based on the Bethe-Salpeter equation…
Compton Scattering off Relativistic Bound States: Two-Photon Vertices, Ward-Takahashi Identities, Gauge Invariance and Low-Energy Limit
Matthias Koll, Ralf Ricken
In a general framework that has been labeled the ``gauging of equations method'', we study the diagrams that contribute to Compton scattering off a relativistic composite system. T…
Weak Decays Of Heavy Mesons In A Covariant Quark Model
Dirk Merten, Ralf Ricken, Matthias Koll +2
In this paper we investigate weak decays of heavy mesons in the framework of a covariant quark model, which is based on the Bethe-Salpeter equation in instantaneous approximation.…
A Relativistic Quark Model for Mesons with an Instanton-Induced Interaction
Matthias Koll, Ralf Ricken, Dirk Merten +2
We present new results of a relativistic quark model based on the Bethe-Salpeter equation in its instantaneous approximation. Assuming a linearly rising confinement potential with…
The Meson Spectrum in a Covariant Quark Model
Ralf Ricken, Matthias Koll, Dirk Merten +2
Within the framework of the instantaneous Bethe-Salpeter equation, we present a detailed analysis of light meson spectra with respect to various parameterizations of confinement in…
