Physicists at CERN have reported the first observations of matter-antimatter imbalance in a subatomic particle 'baryon', offering clues as to why matter dominates in the universe. Particles of antimatter -- called 'antiparticles' -- have the same mass as particles of matter but an opposite charge. According to particle physics models, matter and antimatter should have been created in equal amounts following the Big Bang. However, research indicates a significant imbalance, with matter dominating over antimatter. Understanding why the universe favours matter is one of the most profound questions in physics. The Standard Model of particle physics -- currently the leading model, as it is said to provide the best explanation about the fundamental nature of matter -- predicts that matter and antimatter behave differently. The model theoretically predicts that when a particle is replaced with an antiparticle and its position in space is mirrored, the laws of physics are violated. This ..
Top minds at the world's largest atom smasher have released a blueprint for a much bigger successor that could vastly improve research into the remaining enigmas of physics. The plans for the Future Circular Collider a nearly 91-kilometre loop along the French-Swiss border and below Lake Geneva published late Monday put the finishing details on a project roughly a decade in the making at CERN, the European Organisation for Nuclear Research. The Future Circular Collider (FCC) would carry out high-precision experiments in the mid-2040s to study known physics in greater detail, then enter a second phase planned for 2070 that would conduct high-energy collisions of protons and heavy ions that would open the door to the unknown, said Giorgio Chiarelli, a research director at Italy's National Institute of Nuclear Physics. History of physics tells that when there is more data, the human ingenuity is able to extract more information than originally expected, Chiarelli, who was not ...
