Title: Meson Distribution Amplitudes from Bethe-Salpeter Wave Functions

Abstract: Hadron light-cone distribution amplitudes (LCDAs) were introduced four decades ago in the context of QCD description of hard exclusive reactions. These nonperturbative and scale-dependent functions can be understood as the closest relative of quantum mechanical wave functions in quantum field theory. Within a continuum functional method for QCD, I will discuss some important differences between LCDAs of light and heavy-light pseudoscalar mesons and also present new results for the vector channel which are comparable with Lattice QCD calculations.
