The order p8 mesonic chiral Lagrangian

  • 1. Lund University, Department of Astronomy and Theoretical Physics (Sweden)

Description

We derive the chiral Lagrangian at next-to-next-to-next-to-leading order (NNNLO) for a general number Nf of light quark flavours as well as for Nf = 2, 3. We enumerate the contact terms separately. We also discuss the cases where some of the external fields are not included. An example of a choice of Lagrangian is given in the supplementary material.
