Pion-pion-rho effective lagrangian
WebbIn the Philippines, pionono is more commonly spelled as pianono. It is a rolled sponge cake and is more accurately a type of jelly roll. It consists of a layer of pastry made from eggs, … Webbthe Goldstone bosons, the rho mesons corresponding to the W and Z gauge bosons, and electro-magnetism treated similarly in both cases. To test the model we examine two distinct experimental situations: rstly, decays of the rho meson, and secondly, properties of the pion-pion interaction. Our results are compatible with experiment.

WebbThe effective Lagrangian for π and π' mesons shows the decoupling of the Goldstone pion and the vanishing of the π' leptonic decay constant f π' in the chiral limit, as required by axial-vector current conservation. We derive the excited-state contribution to the axial-vector current of the model using Noether's theorem.
