🚨: In CERN, physicists have observed a rare imbalance in matter and antimatter behavior, offering a possible clue to one of science’s greatest mysteries: why the universe exists. This phenomenon, called violation of charge-parity symmetry (CP), was detected in baryons, particles such as protons and neutrons that make up the majority of matter. By analyzing 80,000 disintegrations of a particle known as lambda-beauty baryon, researchers discovered that its antimatter counterpart disintegrates slightly differently (about 2.5%), a statistically significant deviation with only one among ten million probability that it was a coincidence. And this is important! At the time of the Big Bang, matter and antimatter should have been created in equal quantities and annihilated each other completely, leaving behind a lifeless universe. But that didn't happen. A minimal imbalance favored matter, and that microscopic difference allowed the emergence of stars, planets and life. So far, the violation of CP had only been detected in mesones, which are not ordinary matter. This is the first time such asymmetry has been found in baryons—the particles that make up our physical reality—, bringing scientists closer to understanding how everything we know managed to survive.
