    • Experimental signatures
    • Application to light-, heavy-light and heavy-heavy systems
    • Effects of meson loops on properties of heavy quarkonia
  • Pion Production in nucleon-nucleon collisions
    • Application of chiral perturbation theory (ChPT)
    • Study of isospin violating effects
  • Pion-nucleus scattering
    • High precision ChPT calculations for scattering lengths
