BESIII Experiment Observed the New Evidence of Proton-antiproton Bound State

In the universe, proton is one of the fundamental particles that make up the atomic nucleus, while the antiproton is the antimatter counterpart of proton, having the same mass but with opposite charge. When a proton annihilates with an antiproton. A large amount of energy will be produced. However, some of theorists predicted that proton and antiproton can combine through strong interaction forming a short-lived state known as proton-antiproton bound state.

Recent Progress on Detecting High-frequency Gravitational Waves in Planetary Magnetospheres

Dr. REN Jing, an Associate Professor in the Theoretical Physics Division at the Institute of High Energy Physics of the Chinese Academy of Sciences, along with her collaborators, has introduced a novel detection strategy for high-frequency gravitational waves (HFGWs) for the first time.

HEPS 500 MHz Cryomodule Successfully Developed

HEPS 500 MHz Cryomodule Successfully Developed

The first 500 MHz superconducting accelerator module of the High Energy Photon Source (HEPS), a major national science and technology infrastructure project in China, completed a high-power horizontal test at cryogenic temperature on March 26, 2024. The results exceeded the facility’s design specifications, marking the successful development of the 500 MHz cryomodule and establishing a strong basis for the commissioning and operation of the HEPS accelerator.

LHAASO Discovers Elbow-like Feature in Mean Logarithmic Mass Spectrum of Ultra-high-energy Cosmic Rays

LHAASO Discovers Elbow-like Feature in Mean Logarithmic Mass Spectrum of Ultra-high-energy Cosmic Rays

The Large High Altitude Air Shower Observatory (LHAASO) has accurately measured the cosmic ray all-particle energy spectrum and the mean logarithmic mass in the range of 0.3–30 peta-electronvolts (PeV). It has also discovered an “elbow” feature in the mean logarithmic mass spectrum of cosmic rays. The achievement, “Measurements of All-Particle Energy Spectrum and Mean Logarithmic Mass of Cosmic Rays from 0.3 to 30 PeV with LHAASO-KM2A,” was published online on March 26, 2024.
