INTERESTING NEW RESULTS

On March 23, 2021, CERN announced that the LHCb new results that show possible violations of the Standard Model. The LHCb was comparing two particles beauty quarks decay into. The first particle is an electron and the second is a muon. Muons are elementary particles similar to electrons but significantly heavier. These two particles are types of leptons. According to the Standard Model, when a particle decays into different types of leptons the probability of it decaying into each type should be equal. This concept is referred to as lepton universality. Though muons have more mass than electrons, when a beauty quark decays, they should produce each type in similar abundances.

The new results released by CERN indicate that beauty quarks are more likely to decay into electrons than muons. This violation could indicate physics beyond the Standard Model. These findings are not entirely conclusive yet as it is rare to see beauty quarks decay into electrons and muons. When this event occurs, there is a ratio of 85 muons to every 100 electrons. Although this difference is small it has persisted.
