【 摘 要 】

In this talk we briefly describe some basic elements of chiral perturbation theory, 𝜒 𝑃𝑇, and how the implementation of unitarity and other novel elements lead to a better expansion of the 𝑇-matrix for meson–meson and meson–baryon interactions. Applications are then done to the 𝜋𝜋 interaction in nuclear matter in the scalar and vector channels, antikaons in nuclei and 𝐾- atoms, and how the 𝜙 meson properties are changed in a nuclear medium.
