New Clue to How Matter Outlasted Antimatter at the Big Bang Is Found

Researchers at CERN have discovered a new clue that may help explain the imbalance between matter and antimatter in the universe after the Big Bang. The study found a slight yet significant difference in the way certain particles of matter and antimatter decay. Specifically, the team observed a difference in the rate of decay between particles called B-mesons and their antimatter counterparts. This asymmetry in the decay process suggests that matter and antimatter may not have been created in equal amounts during the Big Bang, potentially providing insights into the fundamental laws of physics that led to the dominance of matter in the observable universe. The findings, published in the journal Physical Review Letters, contribute to the ongoing efforts to understand the mechanisms behind the matter-antimatter imbalance, a long-standing puzzle in cosmology and particle physics. Further investigation into these subtle differences could help unlock the mysteries of the early universe and the evolution of its fundamental constituents.
