Large transverse asymmetry observed in neutral pion production in polarized proton-proton collisions
- New research deepens mystery of particle generation in proton collision -

A group of researchers including scientists from the RIKEN Nishina Center for Accelerator-Based Science, University of Tokyo, Nagoya University, and the Japan Atomic Energy Agency (JAEA) used the spin-polarized Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory in the United States to show that, in polarized proton-proton collisions, neutral pions emitted in the very forward area of collisions—where direct interactions involving quarks and gluons are not applicable—still have a large degree of left-right asymmetry.

FOXSI-3 Succeeded in Focusing Imaging Spectroscopic Observation in Soft X-rays from the Sun for the First Time in the World!

On September 7, 2018 MDT (September 8 in Japan time), an international team from Nagoya University, National Astronomical Observatory of Japan, Kavli IPMU at University of Tokyo, JAXA institute of Space and Astronautical Science, Tokyo University of Science, Minnesota University, University of California at Berkeley and NASA performed the thrid flight of the Focusing Optics Solar X-ray Imager (FOXSI-3) sounding rocket payload for solar X-ray observations from White Sands, New Mexico, USA. A high-speed X-ray CMOS camera developed in Japan was onboard, and the CMOS camera sucessfully performed imaging spectroscopy of X-rays from the Sun in a 0.5-5 keV range for the first time. We expect the FOXSI-3 observation will reveal detailed physical conditions of the solar corona and coronal small scale events.
