“…Until December 2022, the measurements of R K ( * ) gave values around 0.8, deviating from the SM at the 3 σ level and indicating a violation of the electron-muon universality. LHCb has then reported the following new result [87,88]: R K = 0.949 ± 0.05, (73) and a similar finding for the R K * ratio. The new results are now in agreement with lepton flavour universality at the 1 σ level.…”
