Applied Chiral Perturbation Theory

  title={Applied Chiral Perturbation Theory},
  author={Ulf-G. Mei\ssner},
I consider some selected topics in chiral perturbation theory (CHPT) as probed at colliders such as DAΦNE. Emphasis is put on processes involving pions in the isospin zero S-wave which require multi-loop calculations. These include the scalar form factor of the pion, two–photon fusion into pion pairs and Kl4–decays. The physics of the chiral anomaly is… CONTINUE READING
