Growing Expectations for New Physics | |
|
||
| Interesting results have been obtained from neutrino oscillation experiments and precision measurements of muons in recent years. Indication of CP violations in neutrinos was reported and the order of the neutrino mass hierarchy was almost determined. A possibility of a sterile neutrino was also suggested. For muons, the anomalous magnetic moment, g-2, has been precisely measured and the result shows a significant deviation from the prediction calculated by the standard model (SM). These results have attracted many discussions about new physics beyond the SM, such as a suggestion of a new massive particle, a candidate of the dark matter, and a solution to the asymmetry between matter and anti-matter. They can be restrictions on the directions of energy-frontier collider experiments. To consolidate the new physics, many new experimental projects using high-energy and high-intensity accelerators are proposed and conducted. This talk presents the recent results from neutrino oscillation experiments and muon g-2 measurements, possible new physical models beyond the SM, and future prospects of new experiments including the synergy with energy frontier. | ||

Synchrotron Light Illuminates the Origin of the Solar System | |
|
||
| Synchrotron radiation (SR) is unraveling the mystery in the origin of the solar system and life. After a long solitary voyage, Hayabusa2, the successor to Hayabusa, has brought us a capsule carrying scientifically precious samples. Hayabusa achieved the world’s first sample return of materials from an asteroid. Asteroid 162173 Ryugu was the new target of Hayabusa2. It is considered rich in water and organic matter from the birth of the solar system about 4.6 billion years ago. How was our solar system born, and where did the organic matter that constitutes life form? To get the clues, Hayabusa2 landed on Ryugu and successfully collected soil samples. SPring-8 and other SR facilities are now preparing to analyze Hayabusa2’s samples. The state-of-the-art analysis technologies with high sensitivity, resolution, and precision using the brilliant SR will reveal the materials on the asteroid Ryugu opening the door to unveil the origin of the solar system. This talk will be presenting the outline of the Hayabusa project, the progress of sample analysis and other scientific programs, and future perspective. | ||
