Session D07: Physics with Accelerators - Nuclear Physics

Live

The electron-ion collider, proposed by the US nuclear physicists and supported by a wide international community dedicated to hadron physics studies is, since recently, an approved project hosted at the Brookhaven National Laboratory. The collider is a world-wide unique facility dedicated to a long-standing mission: understanding QCD. Its goal is answering to central questions as the emerging of the nucleon properties, mass and spin, from the dynamics of the QCD partons, their three-dimensional structure and the properties of the nuclear systems with high gluon density. These investigations are possible thanks to the availability of polarized electron beams, polarized light nuclear beams and a variety of heavy nuclear beams, the tunable centre of mass energy from 20 to 140 GeV and the high luminosity up to 1034 cm-2s-1 . The time scale for the first physics run is of ten years from now. Intense preparatory activity is now ongoing. The project, its scientific potential and unique opportunities are discussed.

There are several accelerator institutes in Asia offering large experimental facilities to the international researcher community in nuclear and high-energy physics. Ongoing projects include HIFA at IMP, China, BEPCII/BESIII at IHEP, China, RIBF at RIKEN, Japan, and J-PARC and SuperKEKB/Belle II at KEK, Japan. A new Radio Isotope Science Project (RISP) is under construction at RAON in Korea. Furthermore, two energy frontier electron-positron collider projects are being pursued. The International Linear Collider (ILC) is a next-generation experimental facility proposed and designed by the international community of high energy physics, and the baseline of the initial phase of the project has become 250GeV ILC as a Higgs factory since 2017. An intensive Effort is being made to realize the ILC hosted in Japan. The Circular Electron Positron Collider (CEPC), another candidate of a Higgs factory, is planned in China, and its CDR was released in November 2018. Operation, construction and planning of these projects show a rapid development of accelerator science and technology in Asia. I will cover current status and future prospect of large accelerator-based experimental facilities in the Asian region and its impacts on scientific research in nuclear and particle physics worldwide.   

On Demand

The physics of the nucleus and its numerous applications in astrophysics, interdisciplinary research, medicine and industry is one of the dynamically developing domains of science. In particular, physics with Radioactive Ion Beams (RIB) and very high intensity stable-ion beams (SIB) is entering into a new area thanks to next generation RIB and SIB facilities, already in operation or under construction in Asia, North America and Europe. The presentation will focus on future plans of European nuclear physics. A content and importance of the recent Nuclear Physics European Collaboration Committee (NuPECC) Long Range Plan [1] and of integrating activities of the European nuclear physics communities like ENSAR2 and STRONG 2020 will be emphasized. The European flagship facility FAIR [2] and other major European nuclear physics infrastructures in the context of the roadmap established by the European Strategy Forum on Research Infrastructures (ESFRI) [3]~will be presented. Interplay between nuclear, particle and astroparticle physics will be emphasized in the context of the 2018-2020 update of European Strategy for Particle Physics [4].
