Participants of the LHCb experiment at the Large Hadron Collider (LHC), including staff of the laboratory of physics of heavy quarks in the hadron interactions, Novosibirsk State University, received the first indication of a violation of the symmetry between matter and antimatter in decays of baryons. The results are published in the Nature Physics journal.
The LHCb collaboration, working on the LHC, has published the first results indicating a violation of symmetry between matter and antimatter in the decay of the Lambda baryons composed of quarks: b (beauty or pretty), u (up or top) and d (down or bottom) two end-state: a proton and a pion three; proton, pion and two kaons.
According to a senior researcher of the Laboratory of physics of heavy quarks in the hadron interactions of NSU Pavel Krokovnogo, previously CP-violation, or violation of the symmetry between matter and antimatter was observed in decays of K- and B-mesons. In this experiment, LHCb used decays into a proton, pion and two pions or kaons.
The scientist emphasizes that, according to the accepted in the physics of high-energy arrangement, the resulting value is not enough to say about monitoring the phenomenon (it takes five standard deviations or the probability of error of less than one million).
