Chiral unitary theory: application to nuclear problems
arXiv:nucl-th/0101032 · doi:10.1007/s12043-001-0050-8
Abstract
In this talk we briefly describe some basic elements of chiral perturbation theory, $ÏPT$, 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 $ ÏÏ$ interaction in nuclear matter in the scalar and vector channels, antikaons in nuclei and $K^-$ atoms, and how the $Ï$ meson properties are changed in a nuclear medium.
