CERN researchers find first evidence of the violation of charge-parity symmetry in the decay of the strange beauty meson.
Researchers at the European Organization for Nuclear Research have turned to a cutting-edge artificial intelligence algorithm and found evidence of matter-antimatter asymmetry for the very first time. Thanks to AI, the researchers were able to push the boundary of what can be achieved with the particle detector, an organizational press release said.
Scientists believe that when the Big Bang happened 13.8 billion years ago, matter and antimatter were created in equal amounts. Over this extended period of time, however, the CP symmetry has not been maintained, and quantities of matter vastly exceed that of antimatter. , scientists have observed mesons—subatomic particles made out of an equal number of quarks and antiquarks, decay into lighter particles and transform into antimesons and back again in a process called meson mixing.
To achieve this, the scientists at CERN needed to accurately identify mesons from antimesons in the LHC. They used an approach called flavor tagging, which was completed with the help of an advanced AI algorithm. scientists used the AI algorithm to process a sample comprising 500,000 decays of the strange beauty meson into a pair of muons and charged kaons.
The data for the 500,000 decays came from Run 2 of the LHC, which the researchers then combined with data obtained from Run 1. If the CP symmetry is respected, the net output from these measurements should have been zero. However, the combined result was not zero and was found to be similar to predictions made using the Standard Model.
