Vector mesons as dynamical resonances in the Bethe–Salpeter framework
We present the first dynamical calculation of the ρ-meson as a resonance in the Dyson–Schwinger/Bethe–Salpeter framework by including explicit two-pion exchange in addition to the t-channel one-gluon exchange of rainbow-ladder in the interaction kernel. The width is determined from the imaginary par...
