Addendum: Test of lepton universality in beauty-quark decays
The Standard Model of particle physics currently provides our best description of fundamental particles and their interactions.The theory predicts that the different charged leptons, the electron, muon and tau, have identical electroweak interaction strengths.Previous measurements have shown a wide range of particle decays are consistent with this principle of lepton …
