Renormalization of chiral perturbation theory to order p6

Bijnens, J. LU orcid ; Colangelo, G. and Ecker, G. (2000) In Annals of Physics 280(1). p.100-139
Abstract

The renormalization of chiral perturbation theory is carried out to next-to-next-to-leading order in the meson sector. We calculate the divergent part of the generating functional of Green functions of quark currents to O(p6) for chiral SU(n), involving one- and two-loop diagrams. The renormalization group equations for the renormalized low-energy constants of O(p6) are derived. We compare our results with previous two-loop calculations in chiral perturbation theory.
