We use the Covariant Spectator Theory (CST) to calculate the mass spectrum and relativistic vertex functions of mesons as quark-antiquark bound states in which at least one of the quarks is either a charm or bottom quark. The quark-antiquark bound-state equation in CST is, similar to the Bethe-Salpeter equation, an integral equation in which the kernel consists of two-particle irreducible...
We present results for the electromagnetic form factors of the $\rho$ meson obtained within point-form relativistic quantum mechanics. In our formalism for the calculation of the meson current we treat elastic electron-meson scattering as a Poincaré-invariant coupled-channel problem for a Bakamjian-Thomas mass operator. From the resulting invariant one-photon-exchange amplitude we extract the...
An NJL-type three-flavor quark model with a complete set of explicit
chiral symmetry breaking terms is extended to include vector and axial vector
effective interaction terms. A suitable bosonization procedure is implemented
and discussed. The bosonized Lagrangian is written up to quadratic order in the
bosonic fields and the role of the new interactions is analysed in detail. The
model's...
Holographic AdS/QCD models provide a tool for calculating the spectra of glueballs and light mesons and baryons. In this talk we discuss some recent AdS/QCD models that extend the hadronic description to the case of heavy vector mesons.
Then we consider the finite temperature version of such a model in order to represent the thermal effects of a medium like the plasma in the states of heavy...
