Exotic hadrons with charm and bottom flavors

Exotic hadrons are interesting in nuclear physics, because recently many of them have been discovered in experimental studies at accelerator facilities. They are called X, Y, Z, Pc and so on, and many of them possess charm and/or bottom flavors in their contents. They can be multiquark states which is quite different from the conventional hadrons, i.e., baryons and mesons, and their properties are considered to be intimately related to the essence of the strong interaction in the standard theory for elementary particles, i.e., the quark and gluon dynamics. As one of the interesting exotic hadrons, in this seminar, we focus on Tcc as well as the anti-D meson and nucleon interaction, and introduce their recent studies from theory and experiments.
