摘要：

Quantum loops ares studied ill the linear sigma model with scalar and pseudoscalar multiplets and a pl,znar interaction term lambda Tr[Sigma Sigma (dagger)Sigma Sigma (dagger)]. It is shown how quantum loops break the OZI rule and the classical tree-level octet-singlet degeneracy, and how the Goldstone theorem call be maintained also ill an iterative scheme including some multiloop diagrams.
