A new piece in the matter–antimatter puzzle: A fundamental asymmetry in the behavior of baryons

Critical Mass: A new glitch in the cosmic code

New findings at Cern offer tantalising clues to why the universe contains matter rather than antimatter – but answers remain elusive

Matter vs. Antimatter: LHC Discovery Could Explain How Universe Avoided Obliteration

Matter and antimatter should have completely wiped each other out eons ago, leaving the Universe a very empty place.

A new piece in the matter–antimatter puzzle: A fundamental asymmetry in the behavior of baryons

On March 24, at the annual Rencontres de Moriond conference taking place in La Thuile, Italy, the LHCb collaboration at CERN reported a new milestone in our understanding of the subtle yet profound differences between matter and antimatter.

Why is there more matter than antimatter? CERN result offers tantalizing new clue

For the first time, physicists have spotted a difference in the way matter and antimatter baryons decay, which could help to explain a major cosmic mystery. For the first time, physicists have spotted a difference in the way matter and antimatter baryons decay, which could help to explain a major cosmic mystery.

Physics Milestone: Physicists have for the first time demonstrated a difference between antimatter and matter in a baryon – one of the building blocks of all matter. The significant symmetry fracture was found in decays in the particle accelerator LHC at the CERN research center. A "heavier brother" of the proton, the so-called Beauty Lambda Baryon, behaved differently than its antimatter counterpart. This important breakthrough could help solve…
