The 27th International Collaboration Meeting of the Jiangmen Underground Neutrino Observatory Successfully Held at Wuhan University

From January 19 to 23, the 27th International Collaboration Meeting of the Jiangmen Underground Neutrino Observatory (JUNO) was successfully held at Wuhan University. The meeting attracted 350 in-person participants and 15 online attendees from 13 countries and regions, setting a new record for in-person attendance since the establishment of the JUNO collaboration.

First Pulsar Polarization Array Limits on Ultralight Axionlike Dark Matter

First Pulsar Polarization Array Limits on Ultralight Axionlike Dark Matter

Recently, Prof. REN Jing from the Institute of High Energy Physics of the Chinese Academy of Sciences, and collaborators, in partnership with the Parkes Pulsar Timing Array (PPTA) collaboration in Australia, successfully performed the first-ever “pulsar polarization array” (PPA) analysis to detect the ultralight Axion-Like Dark Matter. Leveraging long-term polarization data from the PPTA, the research team established the most stringent observational upper limits to date on the Chern‑Simons coupling strength between ultralight ALDM and the electromagnetic field within the "fuzzy" mass range. The findings were published in Physical Review Letters (Phys. Rev. Lett. 136, 011001 (2026)) on January 7 and were selected as an "Editors' Suggestion" paper.

​LHAASO Uncovers Mystery of Cosmic Ray

​LHAASO Uncovers Mystery of Cosmic Ray "Knee" Formation

The Large High Altitude Air Shower Observatory (LHAASO) released two milestone scientific results, published in National Science Review and Science Bulletin respectively on November 16. These findings not only uncover the key mechanisms of cosmic ray origins but also open a new window for understanding the extreme physical processes of black hole systems.

HEPS Achieved a Historical Milestone

HEPS Achieved a Historical Milestone

On Oct 29, the High Energy Photon Source (HEPS) reached a historic milestone by passing the Chinese Academy of Sciences’ performance acceptance. A key project under the 13th Five-year Plan, HEPS started construction in June 2019. Built over six years, it is Asia’s first fourth-generation synchrotron radiation facility, set to generate the world’s brightest hard X-rays for scientific research.

CEPC Releases the Technical Design Report of Reference Detector

CEPC Releases the Technical Design Report of Reference Detector

The Circular Electron-Positron Collider (CEPC) study group has released the CEPC Technical Design Report of Reference Detector (RefTDR) (arXiv:2510.05260). Following the publication of the Accelerator Technical Design Report at the end of 2023, this detector report signifies that the technical designs of the two core components of the CEPC project—the accelerator and the detector—have both been successfully completed. It lays a decisive foundation for turning this "Higgs factory" from idea into reality.

The 11th DIRAC Users’ Workshop Successfully Hold in IHEP

The 11th DIRAC Users’ Workshop Successfully Hold in IHEP

From September 17 to 20, the "11th DIRAC Users’ Workshop" was successfully held at Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences. It is the first time the DIRAC workshop was hosted in China. The event brought together approximately 50 participants onsite (including around 16 international experts), about 15 experts are joining the meeting online. Attendees included leading specialists in distributed computing, core DIRAC software developers from CERN, as well as experts and scholars from eight major high-energy physics experiments and organizations such as LHCb, JUNO, Belle II, CEPC, ILC, CTA, NICA and Gridpp.
