Description
We investigate heavy hadrons from the QCD instanton vacuum, focusing on the heavy-light mesons and quarkonia.
For the heavy-light mesons, the heavy Wilson line and light-quark zero mode generate a nonlocal interaction, from which an effective meson action is constructed.
This framework is used to study meson masses, decay constants, and nonperturbative HQET parameters.
For quarkonium, the instanton contribution is incorporated into a nonrelativistic Cornell-type potential, and its effects on the mass spectrum are examined.
These results motivate a unified instanton-based effective description of heavy-hadron structure and transitions.
