**Hadronic Atoms in QCD + QED**

by J. Gasser, V.E. Lyubovitskij, A. Rusetsky

**Publisher**: arXiv.org 2009**Number of pages**: 140

**Description**:

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.
