Renormalization of the SU3 × SU3 σ model
We have carried out the renormalization procedure for the SU3 σ model through second order in the presence of symmetry-breaking terms. We show explicitly that no new divergent counterterms are needed other than those required in the symmetric theory. The theory can be completely determined in terms of known masses and the decay constant fπ. © 1973 The American Physical Society.
