The anomalous chiral Lagrangian of order p(6)

Summary, in English

dWe construct the effective chiral Lagrangian for chiral perturbation theory in the mesonic odd-intrinsic-parity sector at order p(6). The Lagrangian contains 24 in principle measurable terms and no contact terms for the general case of N-f light flavors, 23 terms for three and 5 for two flavors. In the two flavor case we need a total of 13 terms if ail external singlet vector field is included. We discuss and implement the methods used to reduce to a minimal set. The infinite parts needed for renormalization are calculated and presented as well.
