**Welcome to RCNP Theory Group [#z2209544] #ref(figures/GroupPhoto190530.JPG,nolink,30%) **About us [#t189815f] Our study covers theoretical hadron and nuclear physics: +Structure of hadrons (protons and neutrons) from quarks and gluons +Construct nuclei from protons and neutrons +Understand the origin of elements by high precision nuclear reaction theory Our aim is to understand the diverse phenomena associated with the strong interaction from the microscopic world of quarks for nucleons to macroscopic world including star phenomena. Quantum chromodynamics confines quarks and breaks chiral symmetry spontaneously, but we do not know their mechanism. Yukawa's interaction by the pion binds the nucleus, but we still can not solve the problem of nuclear structure. It is rather recent that we can describe nuclear reactions to clarify how the elements are formed in the history of the universe. We are approaching these problems by using various methods of theoretical physics of quantum mechanics, relativity and field theory. In performing our research, we discuss and collaborate with many physicists from the world. We also discuss with experimentalists who are working at the RCNP cyclotron, SPring-8, KEK, RIKEN and J-PARC. //Staff members: //Atsushi Hosaka (Professor), Kazuyuki Ogata (Associate Professor), //Kanabu Nawa (Postdoc Fellow), Yuma Kikuchi (Postdoc Fellow), //Kanchan Khemchandani (Postdoc Fellow) //Hideko Nagahiro (Guest Researcher/Nara Women's University), //Takayuki Myo (Guest Researcher/Osaka Institute of Technology) #ref(figures/RCNP-FIG-ver4.png,nolink,50%)
