A particle physics report in the British Nature magazine published on the 14th reported that scientists have detected neutral B meson particles in the Large Hadron Collider (LHC) underground in the European Centre for Nuclear Research (CERN). decay. Since the standard model of particle physics predicts this decay, physicists have been looking for evidence of this decay process for more than 30 years. This new observation confirms the prediction made by the standard model. Scientists hope that the new experiments conducted at LHC can accurately explore the characteristics of this decay. Basic particles are the most basic structure that people can already understand. The standard model of particle physics describes the properties of basic particles and their interactions. By testing the theoretical predictions made by the standard model, it is possible to detect the accuracy of the standard model or make some corrections to it in order to answer questions that are currently not interpretable by the standard model, for example, the origin of antimatter. This time in Geneva, Switzerland, physicists discovered that neutral B mesons decay into muons (like electrons but heavier and can be imagined as an “emphasized†electron), which provides a standard model for particle physics A rigorous test of accuracy, because this decay is very sensitive to the incompleteness of the model. Previous experiments have also found evidence of this decay, but this time it was collected and analyzed by two LHC detectors, the compact muon coil (CMS) and LHC bottom quark experiments. The measurement information of the decay rate is provided, and the result is consistent with the prediction made by the standard model. At the same time, the observation and analysis results of this experiment also impose certain constraints on the expansion of the standard model. Researchers hope that the new experiment conducted by the LHC can more accurately explore the characteristics of this decay. After two years of escalation and preparation, the LHC officially restarted last month and made its first impact after the restart earlier this month in preparation for the second phase of the collision experiment that will begin in June. By then, the total energy of its proton beam will reach a record 13 trillion electron volts.
