The results of the Large Hadron Collider beauty (LHCb) experiment<\/a>, announced at the Moriond conference<\/a> on electroweak interactions and unified theories, strengthen hints of the possibility of a violation of lepton flavour universality.<\/p>\n The measurement made by the LHCb collaboration, compares two types of decays of beauty quarks. The first involves the electron and the second the muon. The electron and the muon, together with a third particle called the tau, are types (or flavours) of leptons.<\/p>\n The SM of particle physics predicts that decays involving different flavours of leptons, for instance the one in the LHCb study, should occur with an equal probability. This feature is known as lepton flavour universality and is usually measured by the ratio between the decay probabilities. In the SM, the ratio should be very close to one.<\/p>\n The new result reveals hints of a deviation from this ratio: the statistical significance of the result is 3.1 standard deviations, which indicates a probability of around 0.1% that the data is compatible with the SM predictions.<\/p>\n
