Abstract

In this talk we briefly describe some basic elements of chiral perturbation theory, χPT, 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.
