Hadronic atoms in QCD + QED

Understand

We review the theory of hadronic atoms in QCD + QED, based on a non-relativistic effective Lagrangian framework.

• We first provide an introduction to the theory, and then describe several applications: meson-meson, meson-nucleon atoms and meson-deuteron compounds.
• Finally, we compare the quantum field theory framework used here with the traditional approach, which is based on quantum-mechanical potential scattering.
