[EX] Baryon-baryon interactions in chiral effective field theory
|講演者||河野 通郎 教授（大阪大学 核物理研究センター）|
Over the last two decades, the description of nucleon-nucleon (NN) interaction in chiral effective field theory has progressed. Based on the symmetry of QCD, together with the properties such as the precision equal to or better than other modern NN potentials for reproducing NN scattering data and the possibility of introducing more than three-body interactions in a systematic way, the ChEFT NN potentials now play a central role in the first-principle investigations of nuclear structure and reactions by using various methods of quantum many-body theory that have been developed around the same period. The ChEFT method is also applied to interactions in the strangeness sector. The seminar outlines the construction of the baryon-baryon interactions in chiral effective field theory.
