BRICS-STARS 2026 Successfully Held in Beijing

The BRICS-Synchrotron Technology and Applications Research School (“BRICS‑STARS 2026”) was successfully held at the campus of the High Energy Photon Source (HEPS) of the Institute of High Energy Physics of the Chinese Academy of Sciences (IHEP, CAS) in Huairou, Beijing, from September 13 to 20. Young researchers, 19 from overseas and 11 from China, from large scientific facilities and institutions across BRICS countries, including the Sirius in Brazil, African Light Source (planning), Siberian Circular Photon Source (SKIF) synchrotron light source in Russia, the Kurchatov Institute, and the Siam Photon Source (SPS) in Thailand, gathered to exchange knowledge with the HEPS team for fourth‑generation synchrotron radiation sources. The school helped participants advance professional skills and broaden research horizons.

Synchrotron Insights Unlock Prussian Blue-mediated Stabilization of Scalable Perovskite Photovoltaics

Synchrotron Insights Unlock Prussian Blue-mediated Stabilization of Scalable Perovskite Photovoltaics

BSRF’s 1W1A and 1W1B beamlines were central to the advance. Engineers built an optimized in situ GIWAXS platform for inert-condition film formation, while XAFS protocols delivered high-quality Fe K-edge data. These facility capabilities directly revealed Prussian-blue-regulated nucleation and cation immobilization in perovskites. The mechanism insight supported 26.9% small-cell, 23.4% mini-module and 22.9% 30×30 cm submodule efficiencies. The work shows how IHEP/BSRF experimental platforms turn advanced characterization into breakthroughs for stable, scalable perovskite photovoltaics.

Next Frontiers in Magnetic Monopole Searches: International Workshop Held at IHEP

Next Frontiers in Magnetic Monopole Searches: International Workshop Held at IHEP

From September 11 to 14, the international workshop “Next Frontiers in Magnetic Monopole Searches” (NFMMS' 26) was held at the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences, in Beijing. The workshop brought together 46 participants from ten countries — theorists, cosmic-ray physicists, particle experimentalists, and instrument developers — to chart the path for the next-generation dedicated search for magnetic monopoles in cosmic rays. At the opening session, Prof. WEN Liangjian, deputy director of IHEP, welcomed the participants and reaffirmed IHEP’s commitment to leading this new experimental program.

From September 14 to 18, the 2nd Annual Meeting of the China-Brazil Joint Laboratory for Synchrotron Science and Technology (CBJSync), jointly built by China’s High Energy Photon Source (HEPS) and Brazil’s Sirius Light Source, was successfully held in Huairou, Beijing. The event marks a solid step forward in deepening bilateral strategic cooperation in the field of fourth-generation synchrotron radiation technologies.

Einstein Probe and LHAASO Reveal a 42-light-year Directed Journey of Cosmic Rays

Einstein Probe and LHAASO Reveal a 42-light-year Directed Journey of Cosmic Rays

A 42-light-year X-ray tail from pulsar PSR J1740+1000, fully revealed by China's Einstein Probe, matches LHAASO's ultrahigh-energy gamma-ray emission. This joint discovery shows high-energy particles from the pulsar wind nebula travel directionally for tens of light-years rather than diffusing isotropically, providing direct evidence for particle escape and propagation in interstellar space. The finding offers a new perspective on "orphan" gamma-ray sources lacking clear counterparts.

BESIII Achieves World’s Most Precise Measurement of Lambda Hyperon Electric Dipole Moment

BESIII Collaboration reports the world's most precise Λ hyperon EDM measurement using quantum-entangled Λ–anti-Λ pairs from J/ψ decays at BEPCII, improving sensitivity by ~1,000× over the previous Fermilab limit to the 10⁻¹⁹ e·cm level, as published in Science on 3 September 2026.

BESIII Experiment Identifies X(2370) as a Glueball Dominated Particle

The BESIII Collaboration confirmed the existence of the long-sought glueball at the International Conference on High Energy Physics in Brazil. After 15 years of research, they identified X(2370) as a pseudoscalar glueball with quantum numbers 0⁻⁺, verifying QCD predictions and marking a crucial breakthrough in strong interaction studies.

LHAASO Identifies the First Variable PeV Gamma-Ray Source

LHAASO Identifies the First Variable PeV Gamma-Ray Source

LHAASO identifies Cygnus X-3 as the highest-energy gamma-ray source known, with particles up to 30 PeV—far beyond galactic accelerator predictions. Its ultra-high-energy flares correlate temporally with GeV emissions and show a 4.8-hour orbital periodicity, enabling precise localization. Published in National Science Review, the study marks the first variable ultra-high-energy gamma-ray source, opening new frontiers in time-domain astronomy and multi-messenger research on compact object physics.

Positron Annihilation Probe Reveals Chemical Short-Range Order in Multi‑Principal‑Element Alloys

To address the longstanding challenge of characterizing chemical short‑range order (SRO) in multi‑principal‑element alloys (MPEAs), the research groups led by Prof. CAO Xingzhong at the Institute of High Energy Physics of Chinese Academy of Sciences (IHEP, CAS) and Prof. LU Yiping at the Dalian University of Technology developed an accurate identification methodology based on positron annihilation spectroscopy. The work is published under the title "Positron annihilation in multiprincipal element alloys for the identification of chemical short‑range‑order structures" in Physical Review Letters [Phys. Rev. Lett. 137, 026101 (2026)].

First Physics Result of the Jiangmen Underground Neutrino Observatory Published in Nature

JUNO released its first physics result as a Nature cover article on June 10, based on over 59 days data. It improved neutrino oscillation parameter precision greatly and won high recognition. Its detector performance paper was also published earlier. Running 700 meters underground, the 20,000-ton detector operates stably. More new findings about neutrinos will be unveiled this summer.
