Corrections to the Weiss-Zumino term in chiral perturbation theory
Summary, in English
All the terms needed to cancel the divergences appearing in one-loop calculations involving the Wess-Zumino term are obtained. We apply this result to the Pγγ and PPPγ vertices, fixing the finite part of the coefficients of the O(p6) terms in the lagrangian with vector meson contributions. In all the cases the corrections improve the agreement between the theoretical predictions and experimental data.
