Rinaldo Baldini-Ferroli and BESIII Experiment

Professor Rinaldo Baldini-Ferroli, a senior scientist of the BESIII International Collaboration, passed away on the evening of February 21, 2026, in Rome, Italy. Rinaldo was affiliated with the Laboratori Nazionali di Frascati in Frascati, Italy, and joined the BESIII International Collaboration in 2008 as a representative of the institution. Rinaldo was also a trailblazer in China-Italy high-energy physics cooperation.

Significant Progress in Unraveling Microscopic Origin of Intertwined Density Wave in Nickelate Superconductors

Significant Progress in Unraveling Microscopic Origin of Intertwined Density Wave in Nickelate Superconductors

A collaborative research team from the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences (CAS), Argonne National Laboratory (USA), Brookhaven National Laboratory (USA), and Arizona State University (USA) has, for the first time, clarified the microscopic origin of the intertwined density wave order in nickelate superconductors by employing synchrotron-based meV-resolved inelastic X-ray scattering (meV-resolved IXS). The related findings have been published on Physical Review X on January 23, entitled "Lattice-charge coupling in a trilayer nickelate with intertwined density wave order" (Phys. Rev. X 16, 011013 (2026)).

AI Technology Leads New Paradigm in Scientific Research at Large-scale Facilities: First Data Analysis Agent for Spallation Neutron Source Released

From January 21 to 22, RZera & Dr.Sai-Rongzai Agent Training Session and Agent Application Seminar was successfully held at the China Spallation Neutron Source (CSNS), Institute of High Energy Physics of Chinese Academy of Sciences (IHEP, CAS). The event was jointly organized by the CSNS Data Analysis Group, the Computing Center of IHEP, and the Greater Bay Area Branch of the National High Energy Physics Scientific Data Center. The seminar aimed to promote exchanges and cooperation in neutron experiment data processing and analysis among various CSNS spectrometers and to advance the intelligent and efficient development of neutron data. The conference brought together experts and scholars from multiple research teams, including CSNS, IHEP Computing Center, and High Energy Photon Source. Attendees included LIANG Tianjiao, Deputy Director of Dongguan Branch of IHEP, QI Fazhi, Director of Computing Center of IHEP, and ZHANG Junrong, Deputy Director of the Neutron Science Department of the Dongguan Branch of IHEP.

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.

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.
