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

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

Neutrino Tomography of Earth: A New Look at the Planet's Interior

Earth's internal structure is traditionally studied using seismic methods and gravimetry. But neutrinos—particles that barely interact with matter—offer a fundamentally different, gentle probe. The IceCube collaboration analyzed 10.7 years of muon neutrino observations with energies from 500 GeV to
