Description
We use the framework of the Dyson Schwinger and Bethe-Salpeter equations to compute Light-Cone Distribution Amplitudes of heavy-light mesons and quarkonia. The corresponding heavy-light Bethe-Salpter amplitudes are projected onto the light front and we reconstruct the distribution amplitudes of the mesons in the full theory.
Also we calculate the strong decay couplings for ρ→ππ, ϕ→KK, K→Kπ, and D→Dπ in a unified and consistent approach based on the impulse approximation, nonperturbative solutions of the quark-gap equation and the Poincaré invariant Bethe-Salpeter amplitudes of vector and pseudoscalar mesons.
