Who’s Who in the World of Particles and Antiparticles

Physicists at LHCb have learned to identify neutral B mesons—particles that can turn into their antiparticles—more precisely. The new method analyzes not individual traits but the entire decay picture, improving accuracy by 35%. This brings us closer to understanding why matter defeated antimatter i

Star explosions accelerate particles to record energies

The LHAASO observatory studied gamma-ray emission from supernova remnant IC 443 and found that particles there are accelerated to record energies with no signs of slowing down. This is direct confirmation: it's star explosions that produce the most energetic cosmic rays bombarding Earth.

Solar Storm Illuminated Magnetic Fields in Space

Usually, cosmic rays arrive evenly from all directions, but when the Sun ejects a magnetic cloud, their paths bend. On November 4, 2021, the LHAASO observatory caught a temporary lopsidedness, offering the first-ever glimpse of invisible magnetic structures in interplanetary space.

Radon Hides Dark Matter

Scientists found that noise in dark matter detectors is caused by radon. Its atoms settle on internal metal grids and, when decaying, mimic signals from elusive particles. The created model matched data from the LUX and LZ experiments. This will help purify future experiments and maybe finally catch
