Recent developments in astronomical spectroscopy and various kinds of top-notched telescopes around the world reveal the element abundances of the Solar system as well as many metal poor old stars. Although such baryonic matter turns out to compose only 4% of the universe, we are living such only 4% baryonic world with other dark matter and dark energy. Therefore it is imperative for the physics to understand the origin of such elements and to identify the dark matter and dark energy.
Hadrons and nuclei are the basic constituents in various nuclear phenomena, which range from the nucleon-nucleon interactions to the birth, evolution, and death of stars. These phenomena occur in various exotic conditions and environments, so apparently they look complicated and independent processes. However, if we are able to understand the properties and interactions of hadrons in a given condition, we can then understand the Nature in such a vast range. For example, if we understand the supernovae explosion, which is thought to be the last stage of the massive star evolution and important sources of the elements produced in the explosion process, we may enumerate the element abundances through the chemical evolution in the galaxy. In the explosion process, one expects tremendous successive nuclear reactions in a millisecond scale, in which many unstable nuclei already decayed in fractions of a second and then participate in the nuclear reaction and imprint their existence in the element abundances.
However, recent new rare isotope beam (RIB) facilities such as FRIB and KoRIA accelerator to be constructed in near future in the US and Korea will provide us with a chance for investigating various aspects of the exotic nuclear structure and their reactions in our Earth. Of course, heavy ion collisions (HIC) at the facilities may shed a valuable light on the equation of state of nuclear and dense matter, test of the standard model, evolution of stars, synthesis of heavy elements, secrets of supernova, and even the fate of the stars. Another important progress in understanding the interactions of the constituents of baryons and the formation of elements will be achieved by the hadron-hadron scattering experiments at the J-PARC. While the RIB facilities will provide information at the level of nucleus, the J-PARC will shed light on our understanding on their building blocks. Therefore, these two activities are complementary to each other. In this program, we will focus on the physics topics which will be investigated by these important facilities. Inviting world-wide experts, we expect to have information on the status of the forefront researches, to discuss problems and issues, and to exchange ideas on the future research direction of these fields. Establishing intimate connection between Japan, China and Korea, we hope to promote human exchanges and collaboration programs. Eventually we aim at building a research and collaboration network in the Asia-Pacific region that leads world-leading research activities in the related fields.
Topics of HaPhy 2013 III
With the recent development of rare isotope (RI) accelerator, we have now lots of experimental data, including static propertoes and related nuclear reaction, for exotic nuclei which are known to play critical roles in the nucleosynthesis in the cosmos. In this workshop, we discuss
1) RI nuclear structure and related nuclear reactions
2) Roles of exotic RI nuclei in the nucleosynthesis
3) R-process and neutrino-process in the supernovae explosion
4) Exotic hyperons in the neutron stars
5) Experimental approaches to RI and nuclear astrophysics
6) Related topics ( RENO 50, BBN...)
