SUMMARY
The upcoming announcement by the LHC on December 20, 2023, will present results regarding lepton universality violations based on measurements of 𝑅(𝐾) and 𝑅(𝐾∗) using data from LHCb Run 1 and 2, totaling an integrated luminosity of 9 fb−1. This analysis employs a data-driven approach to enhance signal purity and addresses residual hadronic backgrounds, marking it as the most sensitive test of lepton universality in rare b-decays to date. The results are expected to align with Standard Model predictions, suggesting that previously noted anomalies in high energy physics may diminish with improved data quality.
